<span>A) 2x + 4y = 38
B) 10x + 3y = 105
Multiplying A) by -5
A) -10x -20y = -190 then adding it to B)
</span><span>B) 10x + 3y = 105
-17y = -85
y = 5
x = 9

Answer:
56 square units
Step-by-step explanation:
I'd recomend using something like "Desmos" to plot the points so then you can see the points and the rectangle. Then count the length and width. For the this rectangle the length was 8 and the width was 7, multiply these and you get the answer of 56 sqaure units.
Answer:
d = 4 units
Step-by-step explanation:
The diameter is twice the radius
d = 2r
d = 2(2)
d = 4 units
Answer:
f= -(6/5)g
Explanation:
We have been given the expression 6f+9g = 3g+f
Solve for f means find the value of f
We will simplify the given expression:
we will collect the values of f at one side and g on the other side
So, rewriting the given expression 6f+9g =3g+f as 6f-f=3g-9g
So, after simplification it will lead to 5f= -6g
After further simplification f= -(6/5)g which is the final result
36. (-)•(-)=(+) 3•12=36 therefore the answer is 36
