X = pens and y = pencils
4x + 7y = 13.25
y = 0.75
4x + 7(0.75) = 13.25
4x + 5.25 = 13.25
4x = 13.25 - 5.25
4x = 8
x = 8/4
x = 2 <===so each pen cost 2 bucks
By definition, the formula for finding the area of a trapezoid is
A = [(b1 + b2) x h] / 2
Where,
b1: Base 1
b2: Base 2
h: height, or distance between bases.
Substituting we have:
A = ((5 + 4) * (2.5)) / 2
A = 11.25 feet ^ 2
Answer:
the area of the seat is:
A = 11.25 feet ^ 2
<span>x2</span>+<span>y2</span>+6x+10y+9=<span>0
that is ur answer :)</span>
here two given sides are 10 and 6,
We use the rule of triangle here:
sum of two sides> third side
checking for each option
Option A: AC=4
4+6>10, 10>10 (false)
So AC cannot be equal to 4, option A is answer.
Answer:
14.2 inches
Step-by-step explanation:
Given
1 inch = 14 feet
Required
Find the equivalent of 199 feet
Write out the given expression;
1 inch = 14 feet
Divide both sides by 14
Let x represent the equivalent of 199 feet in inches;
Such that:
Substitute
becomes
<em>x = 14.2 inches (Approximated)</em>
