So, let’s represent the number as n:
n+7=2n+3
Subtract both sides by 3:
n+4=2n
Now by n:
2n=4
Divide:
n=2
The number is 2
Answer:
83.7°
Step-by-step explanation:
180° : pi
180 : 3.14
X : 1.46
180/3.14 = X/1.46
X = 1.46 × 180/3.14
X = 83.6942675159
X = 83.7°
Answer:
40 in^2
Step-by-step explanation:
Separate the shape into a square and a triangle. Find the measurements of each shape then find the sum.
Cary's age is 9 years MORE than Dan's age.
Cary's age is Dan's age, but with 9 more years added to that.
Here is how we can express that,

In 7 years, Cary will be C+7 years old,
and Dan will be D+7 years old.
In 7 years, the sum of their ages,
(C+7) and (D+7) will equal 93.
Here is how we can express that:

You have a system of two equations involving two unknowns. You have a couple of nice options here. You can apply substitution or elimination to complete the problem.
