Answer:

x=24

Step-by-step explanation:

Since line A and B are parallel, 3x+7 is equivalent to Angle 6 as they are corresponding angles.

We also know that 4x+5+Angle 6 = 180 as they are a linear pair. We can use substitution and substitute 3x+7 for Angle 6...

4x+5+3x+7=180

7x+12=180

7x=168

x=24

Answer:

x= 24

Step-by-step explanation:

Given: A || B

This means that A is parallel to B.

Properties we can make use of when we have parallel lines are corresponding angles (e.g. ∠1= ∠4) and interior angles (e.g. ∠2 +∠4= 180°).

Let's make use of corresponding angles.

∠6= (3x +7)° (corr. ∠s, A||B)

Since D is a straight line and the sum of the angles on a straight line is 180°,

(4x +5)° +∠6= 180° (adj. ∠s on a str. line)

Substitute ∠6= (3x +7)°:

(4x +5)° +(3x +7)°= 180°

Simplify:

(7x +12)°= 180°

7x +12= 180

7x= 180 -12

7x= 168

Divide both sides by 7:

x= 168 ÷7

x= 24

Shannon is selling boxes cookies and candy for a fundraiser. She's sold each box of cookies for $5.25. She also sold one one box
defon

Answer:

The minimum boxes of cookies is 39

Step-by-step explanation:

Let

x ----> the number of boxes of cookies sold

y ----> the number of boxes of candies sold

we know that

The word "at least" means "greater than or equal to"

so

The inequality that represent this problem is

5.25x+8.75y\geq 200

The solution is the shaded area above the solid line   5.25x+8.75y=200

using a graphing tool

The solution is the shaded area -----> see the attached figure

Find out the minimum boxes of cookies needed to sell to reach the goal

assuming only cookies are sold

For y=0

5.25x+8.75(0)\geq 200

5.25x\geq 200

solve for x

x\geq 38.1

Round up

therefore

The minimum boxes of cookies is 39

Identical sweaters are on sale in two different stores. The sale price in store A is 30% off the regular price of $25. The sale
bekas [8.4K]
30% off 25: multiply 25 by .30 to find 30%: 7.5. Now subtract that from the sales price: 25-7.5=17.5
Do the same for store B: .40•30=12. 30-12=18.
So store A is better by $.50 :) hope this helps :)
