Answer:
QRP
Q = 8x-10
R = 7x+6
P = 7x+8
Step-by-step explanation:
Let x be any positive integer, say x=2
P=7x+8=(7*2)+8=22 units
Q=8x-10=(8*2)-10=6 units
R=7x+6=(7*2)+6=20 units
From the above, Q is the shortest and P is the longest side. Therefore, the sides arranged from shortest to longest will be Q, R, P
Cows=10 units
horses=3 units
if 20 cows then
10 units=20 then
1 unit=2
so horses=3 units
1 unit=2
2 times 3=6
6 horses
Answer:
The answer to your question is: 22 apples and 12 bananas
Step-by-step explanation:
a = apples
b = bananas
165a + 120b = 5070
3a + 2b = 90
Solve by elimination
-60(3a + 2b = 90)
-180 a - 120b = -5400
165a + 120b = 5070
-15 a 0 = -330
a = -330 / -15
a = 22
3(22) + 2b = 90
66 + 2b = 90
2b = 90 -66
2b = 24
b = 24/2
b = 12
<u>Answer:</u>
Alva has 7 trucks in each box.
<u>Explanation:</u>
You need to determine the total number of toys Watson has. Watson has 4 (7+2) = 4(9) = 36 toys.
- Set 36 equal to an expression for the number of toys Alva has. Using t for the number of trucks, 36 = 2 (11+t).
Then, solve the equation.
- 36 = 2(11+t) 36 = 22 + 2t 14 = 2t7 = t
So how many trucks are in each of Alva's boxes?
