An obtuse angle is an angle between 90*-180*
X= Desert 2
y= Desert 1 = 9x (because it is 9 times the area of Desert 1)
Add the two areas together.
x + 9x = 40,000,000
10x = 40,000,000
Divide both sides by 10
x= 4,000,000 sqr mi=area of Desert 2
9x= area of Desert 1 = y
9(4,000,000)= 36,000,000 sqr mi
3s + 2p = 85.50....multiply by -1
3s + 4p = 123
--------------------
-3s - 2p = -85.50 (result of multiplying by -1)
3s + 4p = 123
--------------------add
2p = 37.50
p = 37.50/2
p = 18.75 <=== cost of the pants
3s + 4p = 123
3s + 4(18.75) = 123
3s + 75 = 123
3s = 123 - 75
3s = 48
s = 48/3
s = 16 <=== cost of each shirt
Answer:
A. 2
you add 4x + 3x gives you 7x
then you divide by 7 on each side
7 divided by 7x is x
and 7 divided by 14 is 2
Answer:
63 sandwiches
Step-by-step explanation:
Pete and his friend Danny volunteered to bring sandwiches for lunch at a homeless shelter
They brought 7 loaves of bread
Each loaves have 18 slices
They used 2 slices each to make the sandwich
The first step is to calculate the total number of slices
Sinces 7 loaves of bread are used and each of them contain 18 slices then, the total number of slices can be calculated as follows
= 7 ×18
= 126 slices
Therefore since 2 slices of bread is used to make one sandwich then, the number of sandwiches that was made can be calculated as follows
= 126/2
= 63
Hence 63 sandwiches were made for the shelter
