Answer:
D
Step-by-step explanation:
X+26=2x-24
x+26+24=2x
50+x=2x
50=2x-x
x=50
BFG=2x-24
100-24
BFG=76°
Answer:
(5x+1)(x+7)
Step-by-step explanation:
4x^2+26x+6+x^2+10x
5x^2+36x+7
(5x+1)(x+7)
Prove
5x*x + 5x*7 + 1*x + 1*7
= 5x^2 + 35x + x + 7
= 5x^2 + 36x + 7
To find the answer
Divide 4 1/2 minutes by 3/4 meters
First convert 4 1/2 to an improper fraction, which is 9/2
Then divide it, or cross-multiply it with 3/4
(9/2) / (3/4) or (9/2) * (4/3)
= 36/6
Which equals 6
So the answer is
1 meter every 6 minutes
Or if you want it the other way around
1/6 meters per minute
Answer: x=-1 and y=6
Steps:
So two of the equations are, " 8x+y=-2" and " -5x-2y=-7 "
8x+y=-2
8x= -2-y
x= (-2-y)/8
Now place this equation for x on the other equation.
-5 * {(-2-y)/8} -2y=-7
(10 + 5y)/8 -2y = -7
(10 + 5y - 16y)/8 = -7
10 - 11y = -7 * 8
-11y= -56 - 10
y= - 66/-11
y= 6
Now place the value of y in the first equation
8x + 6 = -2
8x= - 2 - 6
x= -8/8
x= -1
Brainliest please if I am correct!
