Last week, Byron bought 5 containers of yogurt and spent $12.88 on other groceries.
This week Cassandra bought 3 containers of the same yogurt and spent $11.50 on other
groceries. How much more money did Byron spend than Cassadra.

1. Let c represent the cost of one container of yogurt. Write
expressions to represent the amount spent by Byron and the
amount spent by Cassandra.

2. Write an expression to represent the difference by subtracting theamount that Cassandra spent from the amount that Byron spent.
Then complete the steps to simplify the expression

3. What expression represents how much more money Byron spent
than Cassandra?

Select all the equations that have {4} as its solution set. 5 + 2x = 3x + 37−x=12x79−3x=12x+19x2+3=10x−21


5 + 2x = 3x + 3

7−x=12x

79−3x=12x+19

x2+3=10x−21

Answers

Answer:

Option 3 (79−3x=12x+19)

Step-by-step explanation:

When replacing x with 4 you will get the answer 67 = 67, which is true! The other three options are not true when replacing x with 4.

Equations 79-3x=12x+19 and x²+3=10x−21 has the solution set {4}.

Given that, the equations that have {4} as its solution set.

What is an equation?

In mathematics, an equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.

1) Solution of an equation 5 + 2x = 3x + 3 is

3x-2x=5-3

⇒x=2

2) Solution of an equation 7−x=12x is

7−x=12x

⇒12x+x=7

⇒13x=7

⇒x=7/13

3) Solution of an equation 79−3x=12x+19 is

12x+3x=79-19

⇒15x=60

⇒x=4

4) Solution of an equation x²+3=10x−21 is

x²+3=10x−21

⇒ x²-10x+24=0

⇒ x²-6x-4x+24=0

⇒ x(x-6)-4(x-6)=0

⇒ (x-6)(x-4)=0

⇒ x=6 or 4

Therefore, equations 79-3x=12x+19 and x²+3=10x−21 has the solution set {4}.

Answer:

27

Step-by-step explanation:

Answer:

$27

Step-by-step explanation:

substitute the value of p (price of the package of henna powder) which has been given as $12 and the value of s (price of the squeeze bottle) which has been stated as $3 into the equation from part b).

since the equation is 3(p-5) + 2s

write 12 instead of p, and 3 instead of s.

then solve the equation.

= 3(12-5) + 2(3)

= 3(7) + 2(3)

= 21 + 6

= 27

Step-by-step explanation:

For number one, you are looking for how many multiplication equations can equal the number given. For example,

C) 12: 1, 12, 6, 2, 3, 4,

For number 2, composite numbers are numbers that are products of two smaller numbers.

For example, 30=15x2, so it is composite. Try dividing the numbers to see if they are composite.

For number 3,

a) two factors: 5 (1, 5)

b) four factors: 15 (1, 15, 3, 5)

c) five factors: 20 (1, 2, 4, 5, 20)

You times whats in the brackets with 23 then remove the brackets which makes it = -71.3 - 23x = 5

Then i would swap the 23x and 5 around which makes it = 71.3 - 5 = 23x

subtract 71.3 - 5

-76.3 = 23x

Divide -76.3 by 23 (Use a calculator) =

Drag each angle measure to the correct location on the image. Each angle measure can be used more than once.

In the figure, two parallel lines are cut by two other parallel lines. The measures of one of the angles is labeled. Find the measures of the other angles and label them.

137° 52° 128° 38°

*then it’s the picture*

Answers

Answer:

In front of the 52, it'll be 52°, that's all I know.

Vertical angles are always congruent. Since the lines are parallel, we can use the Alternate Interior Angle Theorem.

The way I got 128 was by using the fact that the angles would add up to 360 and the Vertical Angle Congruence Theorem. Basically, the formula is x + x + y + y = 360°. If you replace x with 52°, we can deduce that y is equal to 360 - (52 + 52)/2. That gives us 128°.
