Step-by-step explanation:
1.
The Trapezoid Midsegment Theorem states that a line segment connecting the midpoints of the legs of the trapezoid is parallel to the bases, and equal to half their sum.
In this problem you can see that 5x - 1 is the midsegment of the trapezoid, so using the rule:
[tex](21 + 27) / 2 = 5x -1[/tex]
solve:
[tex]48/2 = 5x-1\\24 = 5x - 1\\25 = 5x\\x= 5[/tex]

There were 3 times as many boys as girls in a museum. After 75 boys left and 25 girls entered, there were 2 times as many girls as boys. If 90 children remained, how many children were in the museum at first? *
Answer:
3x=y
3x-y=0
(y-75)+(X+25)=90
X+y=90+50
X+y=140
3x-y+X+y=0+140
4x=140
X=35(girls)
y=105(boys)
children were in the museum at first? *=35+105
=140

at a butcher shop hilda bought beef and pork. she left with 18 8/25 pounds of meat. Express the number of pounds of pork she bought using a decimal. write whether the decimal repeats or terminates
Pls help I’ll give u brain crown
Answer:
Look below.
Step-by-step explanation:
18 8/25 is a mixed number or mixed fraction.
In order to convert a mixed number into decimal form, you need to divide the numerator by the denominator
8 ÷ 25 = 0.32
Next add the decimal (0.32) to the whole number from the mixed fraction
18 + 0.32 = 18.32
This is how many pounds she bought. This decimal terminates.
Using conversion of improper fraction to a decimal, we find that she bought 18.32 pounds of meat, which is a terminating decimal.
The amount of mean she left, in pounds, was of:
[tex]18\frac{8}{25}[/tex]
We want to convert the improper fraction to decimal, which is made adding the decimal fraction to the integer part, that is:
[tex]18\frac{8}{25} = 18 + \frac{8}{25} = 18 + 0.32 = 18.32[/tex]
The division of 800 by 25 is exact(32), thus terminating decimal, and she bought 18.32 pounds.

Answer:
A) Samuel traveled faster in the first 15 minutes than he did in the last 15 minutes
Step-by-step explanation:
This is the only true option. B is incorrect because he traveled a different amount of miles (meaning at different speeds), so he couldn't have traveled at a constant pace. C is incorrect because Samuel traveled faster in the period than the second. D is incorrect because he traveled 6 miles first, than 4 miles. Add them to get a total of 10 miles, not 9.
