Answer:
a) x = 5b) x = 4Step-by-step explanation:
a)
4x - 3 = 2x + 7
4x - 2x = 7 + 3
2x = 10
x = 10 / 2
x = 5
b)
2x + 6 = 7x - 14
6 + 14 = 7x - 2x
20 = 5x
x = 20 / 5
x = 4

Answer:
w= -12
Step-by-step explanation:
okay I understood it now. Here you go.
You’re welcome :)
Answer:
w= -12
Step-by-step explanation:
x both sides by 24
4w + 15 + -33
move the constant to the right and change its sign
4w= -33 -15
calculate the difference ...
4w = -48
divide both sides by 4
w= -12
Huda evaluated the expression below.
Negative 3 (8 minus 5) squared minus (negative 7) = negative 3 (3) squared minus (negative 7) = -3 (9) minus (-7) = 27 - (-7) = 34.
What was Huda’s error?
A. Huda evaluated (3) squared incorrectly.
B. Huda found the product of –3 and 9 as positive.
C. Huda subtracted –7 from 27 incorrectly.
D. Huda did not follow the order of operations.
Answer:
b Huda found the product of –3 and 9 as positive.

Which is the best estimate of 11 and one-fifth divided by 2 and three-fourths?
Answer:
4 should be the answer to the question
Answer:
11 1/5 divided by 2 3/4:
11 1/5 is a bit less than 12, and 2 3/4 is a bit less than 3
The answer, therefore, should be fairly close to 12 ÷ 3
12 ÷ 3 is 4
Answer is 4

your question is very difficult to answer
Answer:
x = 250
Step-by-step explanation:
∠ ABC = 180° - 55° = 125°
The angle at the centre x is twice the angle on the circle , that is
x = 2 × ∠ ABC = 2 × 125 = 250

c = √12^2 + 5^2
c = 13
Kylie is preparing for the science fair that will take place in six weeks. She has three plants that she has grown from seeds, which she considers to have height 0 centimeters, and she is measuring their heights as she applies different treatments to each. The second plant is receiving Plant Food B. After 3 weeks, it is 10 centimeters tall. If it continues growing at this rate, how tall will it be after 6 weeks?
The height of plant B growing at a rate of 3.33 centimeters per week should have a height of 19.98 cms.
What are lines and their slopes?We know lines have various types of equations, the general type is
Ax + By + c = 0, and equation of a line in slope-intercept form is y = mx + b.
Where slope = m and b = y-intercept.
the slope is the rate of change of the y-axis with respect to the x-axis and the y-intercept is the (0,b) where the line intersects the y-axis at x = 0.
First we need two points (x, y) to obtain the slope.
Assuming height to be 'y' and weeks to be 'x'.
Therefore, (0, 0) and (3, 10) are the two points.
Slope(m) = (10 0)/(3 - 0).
Slope(m) = 10/3.
Slope(m) = 3.33
Now, To obtain the y-intercept.
10 = 3(3.33) + b
b = 0.01 Or neglegible.
Therefore y = 3.3x.
Now, In the 6th week, the height of plant B will be,
y = 3.33(6).
y = 19.98 or 20 cm.

what is the vertical change from point A to point B ?
What is the horizontal change to point A to point B?
Answer:
Vertical change= 1
Horizontal change= 2
Rate of change= 1/2
Step-by-step explanation:
The vertical change is how many units you go up on the triangle and the horizontal change is how many units you go left or right on the triangle. The rate of change is the vertical change over the horizontal change. So that is why 1/2 is the rate of change. Have a great day!

Answer:
[tex]\sqrt{21}[/tex] does not belong
Step-by-step explanation:
a rational number is defined by any number that ends or repeats.
[tex]\sqrt{36\\}[/tex] ends because it is just 6
[tex]\frac{2}{3}[/tex] repeats so it is rational
[tex]\frac{1}{5}[/tex] ends becuase it is just 0.2
but [tex]\sqrt{21}[/tex] does not end nor repeat, making it irrational

jared needs to drill holes 2 1/4 inches apart in a 36 inch section of his garage. which expression can he use to figure out the number of holes he will need to drill
Answer: 36 / 2 1/4
Step-by-step explanation:
From the question, we are informed that Jared needs to drill holes 2 1/4 inches apart in a 36 inch section of his garage. The expression that he can use to figure out the number of holes he will need to drill will be:
= 36 ÷ 2 1/4
From the expression we can then calculate the number of hours to drill. This will be:
= 36 / 2 1/4
= 36 / 9/4
= 36 × 4/9
= 16
He'll need to drill 16 holes
