Answer:
<h2>37</h2><h2 />
Step-by-step explanation:
Let our number be “ xy ”
the tens digit is four less than the units digit means y-4=x
Seven times the tens digit plus five times the units digit is equal to 56 means
7x+5y=56
now we have to solve the system:
y-4=x (1)
7x+5y=56 (2)
(1) ⇒ y=4+x
Then we substitute y by 4+x into the second equation like this:
7x+5(x+4)=56
⇔ 7x+5(x+4)=56
⇔ 12x+20=56
⇔ x = 3
now using equation (1) we get : y=3+4 = 7

4m+3+5m the combine like terms. 4m+5m=9m+3 divide 9 by 3 which give you 3, the property is distributive property, combing like term i forgot the last one name
I’m pretty sure the angle in 53 degrees

Answer:
8.33333333333
Step-by-step explanation:
Solution for 3x-7=18 equation:
3x - 7 = 18
3x = 18 + 7
3x = 25 (divide both sides by 3 to get x)
3x/3 = 25/3
x = 8.33333333333
