Smaller number = x
larger number = y

\left \{ {{y+x=61} \atop y=2x+4}} \right.

solve the system of equations by substitution:

(2x+4) + x = 61
3x+4 = 61
3x=57
x=19

Plug x into the top equation and solve for y:

y + (19) = 61
y = 42

A + b = 61       a > b        a = 2b + 4

2b + 4 + b = 61
3b + 4 = 61
3b = 57
b = 19

What would the answer be
Hoochie [10]

Answer:

B.

Step-by-step explanation:

process of elimination. the red dot is not a 1/4 of the number of lines, so it cant be 12.25, 13.625 is impossible because it has a value less than 13, and 12.625 is impossible as well because it has a value less than 12.5 therefore 12.375 is the best answer, and the only correct answer

Crank
I would prefer to solve this in a decimal form
I will show this to u in 2 ways
1:.75::X:2.25
(1*2.25)/.75x
2.25/.75x
X=3

2.25/.75=3

Two equations are given below: a – 3b = 22 a = b – 2 What is the solution to the set of equations in the form (a, b)? (–10, –8)
aliya0001 [1]
Hi Kristian

a - 3b = 22
a = b - 2

We need to solve a = b -2 for a
First, we need to substitute b - 2 for a in a - 3b = 22
a - 3b = 22
b - 2 - 3b = 22
-2b - 2 = 22
 -2b = 22 + 2
-2b = 24
b = 24/-2
b = -12

Now substitute -12 for b in a = b - 2
a = b -2
a= -12 - 2
a= -14

Thus, the solution is a = -14 and b = -12

The correct option is the last one (-14,-12)


If you have questions about my answer, please let me know.


Good luck!

FinnZ [79.3K]
2x+2x+60=180 because the angles have to add up to 180

So you have

4x+60=180

4x=120

x=30
