Answer:
1. 37.5
2. 8
Step-by-step explanation:
1. the smaller triangle and the bigger triangle are similar, so the sides are also similar.
this means that 16/46 = 20/(x+20)
then, just solve that for x
16/46 = 20/(x+20)
divide both sides by 4
4/46 = 5/(x+20)
multiply both sides by (x + 20)
(x+20) * 4/46 = 5
multiply both sides by 46
4x + 80 = 230
subtract 80
4x = 150
divide 4
x = 37.5
2. do the same thing ( still similar triangles)
the equation would be (3x + 1)/10 = (7x - 1)/22
solve
22(3x + 1) = 10(7x - 1)
66x + 22 = 70x - 10
32 = 4x
x = 8
V=vanila
c=chocolate
4v+1c=45
v+c=27
mulitply 2nd equation by -1 and add to top one
-v-c=-27
<u>4v+1c=45 +</u>
<u />3v+0c=18
3v=18
divide by 3
v=6
sub back
v+c=27
6+c=27
c=21
21 choc and 6 van
A.
v+c=27
4v+1c=45
v=number of vanila wafers bought
c=number of chocolate wafers bought
B. 21 chocolate and 7
I got the answer with math because math is fun and tada
Answer:
r equals start fraction cap a minus p over p t end fraction
Step-by-step explanation:
Subtract the term non containing r, then divide by the coefficient of r.
Answer:
3.44 pints of white paint
Step-by-step explanation:
3/5 x 8.6 = 5.16 pints
Clarissa uses 5.16 pints of blue paints
Subtract 5.16 from 8.6 to find out how many pints of white paint did Clarissa use.
8.6 - 5.16 = 3.44 pints of white paint
Answer:
Y=9
Step-by-step explanation:
Because it passes through two points in a straight line, it must have no coefficient for x, just a Y-Intercept equal to the Y of the two points.
