Hi there!
To solve your answer, since we know a = 7, we can easily solve your equation.
But before we go onto that, I want to show you a tip or two about solving equations with variables next to numbers.
When you have a number, and a variable attached to it, it means to multiply.
Now, to make this equation look a little easier, lets rewrite it.
9 × 7 - 5 × 7 = ___
According to PEMDAS, we won't go straight from left-to-right when solving here. We'll skip around a little.
9 × 7 = 63.
5 × 7 = 35.
Now, since we've multiplied the two numbers, its time to subtract them.
63 - 35 = 28. Sooooo........
9 × 7 - 5 × 7 = 28
Hope this helps!
Message me if you need anything else, I'd be happy to help you out! :D
Answer:
A,D,E
Step-by-step explanation:
I took the test
Answer:
there is not enough information
1/2
2
2/4
4/2
Answer:
2
Step-by-step explanation:
To find the slope of a line given two points you could use the formula: .
However, what I'm fixing to do is equivalent to that except I think easier to remember.
You line up the points vertically and subtract, then put 2nd difference over 1st difference.
Like this:
( 3 , 4)
- ( 5 , 8)
---------------
-2 -4
So the slope is -4/-2=4/2=2.
The slope is 2.
Answer:
By changing group of ones into tens
Step-by-step explanation:
Regrouping refers to changing group of ones into tens to make subtraction easy.
Here, we need to regroup 607 -568 .
In subtraction, we start subtracting digits from ones place.
In number 607, digit at ones place is 7 and in 568, digit at ones place is 8.We can't subtract 8 from 7, so, we will try to borrow 1 from the digit at tens place in 607, but digit at tens place in 607 is 0, so it's possible to take 1 from 0.
So, first we will take 1 from 6 ( digit at hundreds place in 607 is 6 such that 6 becomes 5 ) to 0 at tens place which will become 10 then take 1 from 10 to 7 which will then become 17.
Then , we will subtract 8 from 17.
From the figure:
Cross out the 6, make it a 5 and shift 1 which we have subtracted from 6 to 0 such that 0 becomes 10 then cross the 10, make it a 9 and shift 1 which we have subtracted from 10 to 7 such that 7 becomes seventeen .
Answer : D
From the given graph , we can see that
The graph crosses the y axis at 7
So y axis is (0,7)
The graph is increasing at first and reaches (-2,8) and then start decreasing
The graph start increasing at x=-10 and goes on increasing till x= -2
then the graph start decreasing at x=-2 and goes in decreasing till x= 10
The graph crosses the y axis at (0,7), increasing from x=-10 to x=-2 and decreasing from x=-2 to x=10
Answer D is correct
Answer is d
