Vertical angles are always congruent, or of equal measure.
Vertical angle is equal to given angle. Answer is:(2x+11)
12:7
because you add 7 and 5 and then there is the 7 for the book weight
The first thing we are going to do for this case is define variables.
We have then:
x = Number of boys
y = Number of girls
We now write the system of equations:
x / y = 11/9
x = y + 124
Solving the system we have:
x = 682
y = 558
The number of students is:
x + y = 682 + 558 = 1240
Answer:
the total students in the school is:
1240 students

Step-by-step explanation:
<u>Step 1: Set Up</u>
Let's let our number be set by variable <em>n</em>.
We add 7 to it: n + 7
We then double that entire expression: 2(n + 7)
That expression is equal to 82.8: 2(n + 7) = 82.8
<u>Step 2: Solve for </u><em><u>n</u></em>
- [Division Property of Equality] Divide 2 on both sides: n + 7 = 41.4
- [Subtraction Property of Equality] Subtract 7 on both sides: n = 34.4
∴ Caroline's original number is 34.4.
Answer:
Shane must have collect 911 cans.
Step-by-step explanation:
Assume;
Cans collected by Shane = x
So,
Cans collected by Abha = x+178
Inequality
Cans collected by Shane + Cans collected by Abha ≥ 2,000
x + x + 178 ≥ 2,000
2 x ≥ 2,000 - 178
2 x ≥ 1,822
x ≥ 911
Shane must have collect 911 cans.
