Answer:

Step-by-step explanation:

Since y is equal to 9 and z is equal to 3, we do 10 x 9 - 7 x 3. 10 times 9 is 90, and 7 times 3 is 21.

Then, we do 90-21. 90-21=69. Therefore, 10y-7z = 69.

-144 is -1 x 2a x 3b what is the sum of a+b?
BigorU [14]
-144= -1×2a×3b
144=2a×3b
144= 6ab
24= ab

a,b could b any two factors that have a product of 24
For example a,b could = 6,4 or 8,3 or 24,1 

Answer:
This question is tricky because it could have multiple answers: for example is a,b= 6,4 then a+b= 10, but if a,b=24+1=25. So, the answer is that the sum of a+b varies depending on which 2 factors of 24 a and b are equal to. Does this make sense?

Wht is 84 is 74% of what number
Elina [12.6K]
'is' in mathematics means equal
'of' in mathematics means multiplication

percent means over 100

84 = 74% * x

84 = 74/100 * x

84 = 37/50 * x

Multiply 50/37 on both sides, so we can isolate 'x'

85 * 50/37 = x

x = 4250/37

x ≈ 114.864865

84 is 74 percent of <span>114.86</span>.
