Answer:
1.75p + 1.50(p + 6) = 22
Step-by-Step:
p = peaches, m = mangos
1.75p + 1.50m = 22
m = p + 6
1.75p + 1.50(p + 6) = 22
1.75p + 1.50p + 9 = 22
1.75p + 1.50p = 22 - 9
3.25p = 13
p = 13 / 3.25
p = 4 <====== she bought 4 peaches
m = p + 6
m = 4 + 6
m = 10 <===== she bought 10 mangos
check...
1.75p + 1.50m = 22
1.75(4) + 1.50(10) = 22
7 + 15 = 22
22 = 22 (correct)
Answer: D. 3 x 10^7
Step-by-step explanation: 9.6/3.2=3 and 10^9/10^2 is 9-2=7, so 10^7, so it would be 3 x 10^7.
A) -2, -1
(solve the second equation for x (subtract 2y to the other side, then divide by 2 so x=-y-3) then plug that equation into the x value of the first equation to get y=-1; plug y=-1 into the second equation to get x=-2)
Area of a parallelogram = b*h (base*height)
b= 12cm
h= 18cm
Therefore:
= 12*18 cm
Area of the parallelogram = <u><em>216cm</em></u>
i believe it is -5 over 9
