Answer:
x = 6
y = 7
Step-by-step explanation:
2x - y = 5
x + y = 13
2x - y = 5
y = 2x - 5
x + y = 13
x + 2x - 5 = 13
3x - 5 = 13
3x = 18
x = 6
y = 2x - 5
y = 2 ( 6 ) - 5
y = 7
Volume of prismatic solid = area of base × height
Volume of a pyramid = 1/3 × area of base × height
here, A pyramid is given whose base is a square of side 7 inch and height is 8.5 inch.
Volume = 1/3 × 7^2 × 8.5 in^3
= 138.83 in^3
To the nearest whole number, volume = 139 in^3
Answer and Step-by-step explanation:
In this inequality, we are solving for r. Just think of this as a normal equation, and worry about the sign at the end.
First, add 5 to both sides.
8r > 80
Now divide by 8 to both sides.
r > 10
So, r is greater than 10.
[ If the inequality had a negative number being divided, then the sign would flip.
For example:
-2x > 4
To solve this one, you would divide by -2 to both sides. Then, you would flip the sign.
x < 2 ]

Hope this helps. You should transfer them into fractions, change to common dominators. then subtract and then you get your final answer, you may reduce it from there or not.
Factors of 56 that add up to 30
56 = 2*28
so the factors are 2 & 28
and 2 + 28 = 30
