First you would do parenthesis according to the PEMDAS(Parenthesis, Exponents, Multiply, Divide, Add, Subtract) Rule
4 -2(-5a -10) = 30
4 + 10a + 20 = 30
Now you need to add 4 and 20 because they are on the same side
24 + 10a = 30
Now subtract 24 on both sides
24 + 10a = 30
-24. -24
10a = 6
Last divide 10 from both sides
10a/10. = 6/10
a= 6/10
Last simplify (optional but recommended)
a = 3/5 or 0.6
Hope this helped :)
A = 0.6
You would write the equation like this:
24-10n=64+8n
Answer:
y = 3x –5
Step-by-step explanation:
for slope-intercept form, y = mx + b
find the slope, m
(-8 -4)/(-1-3) = m
-12/-4 =m
3 = m
Substitute for m and use either coordinate for y and x to calculate b
4 = 3(3) + b
4 = 9 + b. Subtract 9 from both sides
4 –9 = b
–5 = b. Rewrite the equation with the calculated values for m and b
y = 3x –5
Answer:
14
Step-by-step explanation:
or 16
Answer:
5² = 25
Step-by-step explanation:
log5 25 = 2
log(b) (x) = (y)
make b^(y) = (x)
5² = 25
I hope this helps!
