Answer:

10

Step-by-step explanation:

So because AC is intersected at the middle, or the midpoint, being E, you can say that both sides of AC; AE and EC, are equal to each other. You can make 4x-3=3x-1 and combine like terms to get X on one side by itself. First, you want to subtract 3x from both sides to move the x from left side and only have it on the right. You should x-3=-1. Then, you want to remove the -3 from the left side and bring it to the right to have x by itself. To cancel the -3 on the left side you have to add 3 on both sides. You should have x=2. Now that you have x, you can plug it into both AE and EC, then add them together. You should have 5 for AE and 5 for EC, and adding them up makes 10. Hope I could help :)

A florist gathered data about the weekly number of flower deliveries he made to homes and to businesses for several weeks. He us
shutvik [7]

Answer:

The number of deliveries that are predicted to be made to homes during a week with 50 deliveries to business is 87 deliveries

Step-by-step explanation:

The data categorization are;

The number of home deliveries = x

The number of delivery to businesses = y

The line of best fit is y = 0.555·x + 1.629

The number of deliveries that would be made to homes when 50 deliveries are made to businesses is found as follows;

We substitute y = 50 in the line of best fit to get;

50 = 0.555·x + 1.629 =

50 - 1.629 = 0.555·x

0.555·x = 48.371

x = 48.371/0.555= 87.155

Therefore, since we are dealing with deliveries, we approximate to the nearest whole number delivery which is 87 deliveries.

Mary McDonald makes mugs in Miami. She makes two sizes of mugs: a small mug that she sells for
Hitman42 [59]

Answer:

4 small

8 large

Step-by-step explanation:

s - small mug

l - large mug

Yesterday she had 200 at start of day

at end of day 188 left, so she sold 12 mugs

(1)   s + l = 12

(2)  2.50s + 5.75l = 56.00

Solve for l in (1)

l = 12 - s

substitute in l = 12 - s into (2)

2.50s + 5.75(12-s) = 56.00

2.50s + 69.00 - 5.75s = 56.00

-3.25s + 69.00 = 56.00

-3.25s = -13.00

s = 4

to find l substitute s = 4 into (1)

4 + l = 12

l = 8

Answer:

C.

Step-by-step explanation:

red: 3/8 sheet per toy

20 × 3/8 = 60/8 = 56/8 + 4/8 = 7 1/2

yellow: 5/8 sheet per toy

20 × 5/8 = 100/8 = 50/4 = 25/2 = 12 1/2
