First distribute (multiply):
17.5 m + 7m = 49
now add variable m:
24.5 m= 49
now divide 24.5 in order tp isolate m:
24.5m ÷24.5= 49 ÷ 24.5
m= 2
so now we know that m equals 2:
m=2

Two integers have a sum of 42 and a difference of 22. The greater of the two<br> integers is
DochEvi [55]
Let
x = larger integer
y = smaller integer

The two integers (x and y) have a sum of 42 which means they add to 42

x+y = 42

solve for y to get 

y = 42-x

simply by subtracting x from both sides

---------------------------------------------------

The two integers have a difference of 22. This translates to "subtract the values and the result will be 22", i.e.,

x-y = 22

Plug in y = 42-x. Solve for x

x-y = 22
x-(y) = 22
x - (42-x) = 22
x - 42 + x = 22
2x - 42 = 22
2x - 42+42 = 22+42
2x = 64
2x/2 = 64/2
x = 32

If x = 32, then y is...
y = 42-x
y = 42-32
y = 10

Therefore, 
x = 32
y = 10

The final answer is 10

Jake is making bracelets to give to his sisters. He uses 4 rainbow charms and 8 white star charms for his younger sister's brace
kolbaska11 [484]

Answer: Yes.

Step-by-step explanation: 4:8 simplifies to 1:2, since he used half as many rainbow charms as he did white stars. 5:10 also simplifies to 1:2. If they both have half as many rainbow charms as white, then both of his sister’s bracelets keep the same ratio.
