A trapezoid has an area of 42 square miles. One base is 4 miles long. The height measures 6 miles. What is the length of the oth
loris [4]

The length of other base of trapezoid is 10 miles

Step-by-step explanation:

The formula for area of trapezoid is:

A=\frac{h}{2}(b_1+b_2)

We know that

A = 42 square miles

b_1 = 4 miles

h = 6 miles

Putting the values

42=\frac{6}{2}(4+b_2)\\42=3(4+b_2)\\42=12+3b_2\\Subtracting\ 12\ from\ both\ sides\\42-12=12+3b_2-12\\3b_2=30\\Dividing\ both\ sides\ by\ 3\\\frac{3b_2}{3}=\frac{30}{3}\\b_2=10\ miles

The length of other base of trapezoid is 10 miles

What is 4x + 6 = -x + 1​
Kamila [148]
Ok so let’s write out the problem
4x+6=-x+1
We first want to get the x’s on one side and the numbers on the other

4x+6=-x+1
+x. +x

5x+6=1

Now we want to get the 6 over


5x+6=1
-6. -6

5x=5

Divide by 5 to get the x alone
X is equal to 1

2[2y-1]+5=19 what are the solutions?
skelet666 [1.2K]

Answer:

y = 4

Step-by-step explanation:

2[2y-1]+5=19   (by PEDMAS, distribute parentheses first)

(2)(2y) - (2)(1) + 5 = 19

4y - 2 + 5 = 19

4y +3 = 19    (subtract 3 from both sides)

4y = 19 - 3

4y = 16  (divide both sides by 4)

y = 16/4

y = 4
