Answer:
x=13 and y =6
Step-by-step explanation:
y=x-7
y=6
Substitute y=6 into the first equation
6 = x-7
Add 7 to each side
6+7= x-7+7
13 = x
x=13 and y =6
Answer:
W=3
Step-by-step explanation:
(6w + 4w)/48=5/8(taking lcm)
6w+4w=5/8*48
10w=30
W=3
Thanks for putting qsn, makes me remember this againa
Answer:
8x^3 + 4x^2 + 4x -7
Step-by-step explanation:
Add like terms.
First of all, to find the slope, you need to subtract the y's in the numerator over the x's in the denominator. Then you use Y-Y₁=slope(X-X₁) using either of the two points. If you want to simplify it further into slope-intercept form, you need to distribute on the right side of the equation.
Answer:
V=1890mm
Step-by-step explanation:
You must use its formula: which is
V=(Length x height x width) / 3
V=(15x18x21)/3
V=5670/3
V=1890mm
