Answer:
c.x=8
d.x=2 5/6
e. x=4
Step-by-step explanation:
c.
(2x-1)/3=5
2x-1=15
2x=16
x=8
d.
(6x+1)/2=8
6x-1=16
6x=17
x=17/6=2 5/6
e.
(7x-3)/5=5
7x-3=25
7x=28
x=4
We have that
<span>35 + 30s - 45t
case A)
</span>7⋅(5+30s−45t)---> 35+210s-315t-----> is not <span>equivalent
case B)
</span>5(7+6s−9t)----> 35+30s-45t------> is equivalent to 35 + 30s - 45t
case C)
(−35−30s+45t)×(−1)----> 35+30s-45t---> is equivalent to 35 + 30s - 45t
case D)
10×(3.5+3s−4.5)----> 35+30s-45----> is not equivalent
case E)
( 35/2 - 15s + 45/2t) ⋅ (-2)--->-35+30s-45t---> is not equivalent
the answer is
<span>B. 5(7+6s−9t)
C. (−35−30s+45t)×(−1)</span>
Answer:
175
Step-by-step explanation:
I would assume you are asking what 2 + 2 + 9 * 19, and that the image is merely advertisement and irrelevant info for the question.
Anyway, we are solving 2 + 2 + 9 * 19.
<u>PEMDAS: Parenthesis, Exponents, Multiplication, Division, Addition, Subtraction:</u>
That is the order of operations. We can apply that in your equation.
Since multiplication comes before addition/subtraction, we are solving 9 * 19 first. That gives 171.
Now for addition:
2 + 2 + 171 = 4 + 171.
4 + 171 = 175.
Thus, our final answer is 175.
