Answer:
She had 38!
Step-by-step explanation:
28-9 is 19 then just multiply that by two which is 38
700 times 3 is 2,100, You get 700 from estimating 697
First, you want to divide 420 by 180. Then, divide 54 by 180. Lastly, you want to multiply the answers of the two together.
-
420/180= 2.3
54/180= 0.3
2.3 * 0.3 = 0.69
*You just take it step by step. Hope I helped. :)
1: 200-75= r
2: 73-29= v
73-29=44
v=44
Answer:
(x, y ) = ( , )
Step-by-step explanation:
given the 2 equations
4x + 2y = 7 → (1)
y = 5x → (2)
Substitute y = 5x into equation (1)
4x + 2(5x) = 7
4x + 10x = 7
14x = 7 ( divide both sides by 14 )
x = =
substitute this value into equation (2)
y = 5 × =
