Answer:
15/2
Step-by-step explanation:
Hello,
the area of a triangle is b*h/2
we can set BC as the base because AC is harder to calculate.
Then we draw an imaginary height.
There's no way to really explain, but the height would be 5 here, since 3 - -2 = 5
The base is 3
3*5/2 = 15/2

Answer: 30 pairs of shorts
21x+420=35x
subtract 21x from both sides of the equation.
420=14x
get rid of the x by division
420/14
you get 30 =x
To solve this question, you need to do 421 divided by 9.
421 divided by 9 will get you a long number, which is 46.7777778.
Round your number up by the hundredths place. You will get 46.78.
The average speed in miles per hour would be 46.78 MPH.
A scale model: 25 inches high <span>with a base length of 5 inches,
</span>the real monument: 550 feet high <span>with a base length of x feet⇒
25:5=550:x
5*550=25x⇒x=2750/25
x=110
</span><span>The base length of the real monument is 110 feet.</span>
The steps are to first distribute the 1/3 into (x-9) and then to move the +6 on the left over to the right:
First distribute:
y + 6 = 1/3(x-9) becomes y + 6 = 1/3x-3
Now subtract 6 from both sides:
y = 1/3 x - 3 - 6
y = 1/3 x - 9
