Ok, so first you solve whatever is in the parentheses.
(28 • 5-5 • 190)-2•228
28• 5 = 140
Then 5 •190 = 950
Then multiply 950 • 140 = 133,000
Then it should look like this:
133,000-2•228
Multiply 2 • 228 = 456
Then subtract 456 from 133,000.
The answer should come out to 132,544.

write an algebraic expression for this word problem. An orange contains 62 calories which is x fewer calories than a nectarine.

nasty-shy [4]

Answer:

n = 62 + x

Step-by-step explanation:

From the problem given, it is clear that the orange has LESS calories than a nectarine. <em>HOW much less? "x" less.</em>

<em />

Also, orange has 62 calories. So, nectarine MUST HAVE 62 + x calories.

<em>If we let nectarine's calories be n, we can write:</em>

<em>n = 62 + x</em>

Write an equation parallel to y= -5/2x + 9 that passes through the point (-6,7) brainly

frozen [14]

Answer:

Step-by-step explanation:

If two lines are parallel, that means their slopes are equal.

And we also know that the line must pass through (-6,7)

And with our point-slope equation, we get the equation:

$y-7 = -\frac{5}{2} (x+6)$

$y - 7 = -\frac{5}{2} x-15\\y= -\frac{5}{2} x-8$ <------ Answer

Hope that helps!
