I need to solve these two equations using either substitution or elimination
1/4x - 1/2 = 5
3x + 2/3y = -40
Answer:
y = -15
x = -10
Step-by-step explanation:
1/4x - 1/2 = 5 (1)
3x + 2/3y = -40 (2)
Multiply (1) by 4
1/4x - 1/2 = 5
1/4x * 4 - 1/2y * 4 = 5 * 4
4/4x - 4/2y = 20
x - 2y = 20 (3)
Multiply (2) by 3
3x + 2/3y = -40 (2)
3x * 3 + 2/3y * 3 = -40 * 3
9x + 6/3y = -120
9x + 2y = -120 (4)
x - 2y = 20 (3)
9x + 2y = -120 (4)
Using elimination method, Add (3) and (4)
9x + x = -120 + 20
10x = -100
x = -100/10
x = -10
Substitute x = -10 into (3)
x - 2y = 20 (3)
-10 - 2y = 20
-2y = 20 + 10
-2y = 30
y = 30/-2
y = -15
y = -15
x = -10

What is the square root of 49/900
The square root of 49/900 is 7/30 according to the given question, it can be done through simplification process.
To find the square root of 49/900, we can simplify the fraction first:
The square root of a number is a mathematical operation that determines a value which, when multiplied by itself, yields the original number. In simpler terms, the square root of a number "x" is the value "y" such that y multiplied by y equals x. The square root is denoted by the radical symbol (√).
49/900 = [tex](7^2)/(30^2)[/tex]
Taking the square root of the numerator and denominator separately, we get:
√ [tex](7^2) /[/tex]√([tex]30^2[/tex])
Simplifying further, we have:
7/30
Therefore, the square root of 49/900 is 7/30.

Stephan has a piece of wood that measures 18 inches long and 12 inches wide. He wants to make a tray with sides 2 inches high. Maurice says that he can make a tray that has a base measuring 10 1/2 inches by 10 1/2 inches. Is he correct?
Answer:
he isn't
Step-by-step explanation:
The wood has dimensions of 18 x 12
If He wants the tray to have a height of 2, subtract 2 x 2 from both the length and the width
18 - 4 = 14
12 - 4 = 8
the highest possible dimensions of the tray can be 14 x 8
10 1/2 x 10 1/2 is greater than 14 x 8. so he is not correct

In the circle below, suppose m VUX = 152° and mZUVW = 77º. Find the following.
(a) m ZVUX =
(b) m ZUXW =
Given:
In the circle, [tex]m(\overarc{VUX})=152^\circ[/tex] and [tex]m(\angle MUV)=77^\circ[/tex].
To find:
The following measures:
(a) [tex]m\angle VUX[/tex]
(b) [tex]m\angle UXW[/tex]
Solution:
According to the central angle theorem, the central angle is always twice of the subtended angle intercepted on the same same arc.
[tex]m(VUX)=2\times m\angle VWX[/tex]
[tex]152^\circ=2\times m\angle VWX[/tex]
[tex]\dfrac{152^\circ}{2}=m\angle VWX[/tex]
[tex]76^\circ=m\angle VWX[/tex]
In a cyclic quadrilateral, the opposite angles are supplementary angles.
UVWX is a cyclic quadrilateral. So,
[tex]m\angle VUX+m\angle VWX=180^\circ[/tex] [Opposite angles of a cyclic quadrilateral]
[tex]m\angle VUX+76^\circ=180^\circ[/tex]
[tex]m\angle VUX=180^\circ-76^\circ[/tex]
[tex]m\angle VUX=104^\circ[/tex]
Now,
[tex]m\angle UXW+m\angle UVW=180^\circ[/tex] [Opposite angles of a cyclic quadrilateral]
[tex]m\angle UXW+77^\circ =180^\circ[/tex]
[tex]m\angle UXW=180^\circ-77^\circ[/tex]
[tex]m\angle UXW=103^\circ[/tex]
Therefore, [tex]m\angle VUX=104^\circ[/tex] and [tex]m\angle UXW=103^\circ[/tex] .

-15,-10,-4, 3, 11, ______
Given:
The sequence is:
-15,-10,-4, 3, 11, ______
To find:
The next number.
Solution:
We have,
-15,-10,-4, 3, 11, ______
Here, the difference between two consecutive terms are:
[tex]-10-(-15)=-10+15[/tex]
[tex]-10-(-15)=5[/tex]
Similarly,
[tex]-4-(-10)=6[/tex]
[tex]3-(-4)=7[/tex]
[tex]11-3=8[/tex]
It is clear that the difference difference between two consecutive terms is increasing by 1. So, the next difference must be (8+1)=9.
Let the next number be x. Then,
[tex]x-11=9[/tex]
[tex]x=9+11[/tex]
[tex]x=20[/tex]
Therefore, the next number of the sequence is 20.

Solve the system of equations using the elimination method.
Let's solve your system by elimination.
8x+y=−16;3x−y=5
8x+y=−16
3x−y=5
Add these equations to eliminate y:
11x=−11
Then solve: 11x=−11 for x:
11x=−11
11x
11
=
−11
11
(Divide both sides by 11)
x=−1
Now that we've found x let's plug it back in to solve for y.
Write down an original equation:
8x+y=−16
Substitute: −1 for x in 8x+y=−16:
(8)(−1)+y=−16
y−8=−16(Simplify both sides of the equation)
y−8+8=−16+8(Add 8 to both sides)
y=−8
Answer:
x=−1 and y=−8
Answer:Multiply each equation by a suitable number so that the two equations have the same leading coefficient.
Subtract the second equation from the first.
Solve this new equation for y.
Substitute y = 2 into either Equation 1 or Equation 2 above and solve for x.

Answer:
8 students in each van, 22 students in each bus
Step-by-step explanation:
Let's say v is number of students in each van
and b the number of students in each bus.
Let's make the equations:
8v + 8b = 240
4v + 1b = 54
8v + 8b = 240
v + b = 30
b = 30 - v
now let's use b = 30 - v and insert it into 4v + 1b = 54
4v + (30 - v) = 54
3v + 30 = 54
3v = 24
v = 8
b = 30 - v = 30 - 8 = 22

Lisa's bedroom is 6 meter long and 4 meters wide how much carpet will Lisa need to cover the whole floor of her bedroom?
Answer:
24 m²
Step-by-step explanation:
Given that:
Dimension of bedroom = 6 meter by 4 meter
To obtain how much carpet Lisa would need to cover the floor of her bedroom, we calculate the area of the room.
From the dimension given, the area of the room can be obtained using the Area if a rectangle formular :
Area of room = Length * width
Area of room = 6m * 4m
Area of room = 24 m²
Carpet required is 24m² of carpet
Answer:
24m

What is g(-3) for g(1) = (x + 7) + 2?
Answer:
x9
Step-by-step explanation:
i dunno if correct
Answer:
6
Step-by-step explanation:
Since you're given g(-3), set up the equation to look like this:
g(-3) = (x+7) + 2
Then plug in the g(x):
g(x) = (-3 + 7) + 2
Use PEMDAS to solve the equation:
g(x) = (-3 + 7) + 2
g(x) = (4) + 2
g(x) = 6
Abigail and Grace collected clovers. Abigail collected clovers with
4 leafs and Grace collected clovers with 5 leafs. They counted the
number of leafs in both collections and realized that it is the
same. What is the least number of leafs that each collection must
have?
Answer:
20
Step-by-step explanation:
To find the least number of leafs that each collection must have, we find the L.C.M of both numbers. So L.C.M of 4 and 5.
The prime factors of 4 = 2²
The prime factors of 5 = 5
So L.C.M of 4 and 5 = 2² × 5 = 20
So, the least number of leafs that each collection can have is 20 leafs.
