X+y=70
x=2y-5
x=larger number
y=smaller number
now plug in the value of x to only have one variable in the equation...
Way to solve for y:
(2y-5)+y=70
3y-5=70
add 5 on both sides...
3y=75
divide by 3 on both sides
y=25
1st way to solve for x:
now plug in y in the original equation...
x+25=70
subtract 25 on both sides...
x=45
2nd way to solve for x:
plug in y for the second equation...
x=25(2)-5
x=50-5
x=45
answer: the two numbers are 45 and 25.
The answer is 56 ft
The perimeter of the rectangle with width w and length l is:
P = 2w + 2l
We know:
w = 7 ft
l = 3w = 3 * 7 = 21 ft
P = 2w + 2l
P = 2 * 7 + 2 * 21
P = 14 + 42
P = 56 ft
Answer:
x · 5 ≥ 17
Step-by-step explanation:
Answer:
121°
Step-by-step explanation:
<B = 9x - 5°
<D = 10x - 19°
<B = <D ( being opposite angles of parallelogram)
9x - 5° = 10x - 19°
10x - 9x = 19° - 5°
x = 14°
Now
<B = 9x - 5°
= 9 * 14° - 5
= 121°
