Answer:
6 units
Step-by-step explanation:
The formula for a trapezoid is ((b1+b2)/2)h.
Here, we see b1 = 8 and b2 = 17.
If the area of the trapezoid is 75, we can make the equation :
75 = ((8+17)/2)x , where we would solve for x.
First, we simplify the right side of the equation :
75 = (25/2)x
Multiply both sides by 2 to get rid of the "/2"
150 = 25x
Then divide both sides by 25.
6=x
Answer:
Step-by-step explanation:
<u>Temperatures given:</u>
<u>Descending order of the numbers is:</u>
Correct choice is E
75 + 10 = 85
85 - 10 = 75
85 - 75 = 10
There is nothing to solve for.
Answer:
a₅=27.
Step-by-step explanation:
1) according to the condition the given subsequence is arithmetic sequence. It means, the a₁=7 and d=5, then
2) a₅=a₁+4*d; => a₅=7+4*5=27.
A) SUBSTITUTION: 4x + 3(-2x +8)=16
4x + -6x + 24 = 16
-2x= -8
x= 4
y= 0
b) ELIMINATION:
12x -8y = -76
-12x -15y = -39
-23y= -115
y=5
x= -3
c) ELIMINATION:
-12x+28y=36
12x-9y=21
19y= 57
X=4
y=3
d) SUBSTITUTION:
-4(23 -3y) +5y=-7
-92+12y+5y =-7
-92 +17y = -7
17y = 85
y=5
x=8
