Susan began counting backwards from 1298 by 4's saying one number every 5 seconds. At the same time Jim begins counting forward
SpyIntel [72]
1298 - 4x =171 + 3x

Add 4x to both sides

1298 = 171 + 7x

Subtract 171 from both sides

1127 = 7x

Divide by 7 on both sides


x = 161

They will both say the number 161 at the same time.

Which statements are correct interpretations of this graph?
Keith_Richards [23]

Answer:

✅6/10 of a page is edited per minute

✅3 pages are edited every 5 min

Step-by-step explanation:

On the graph, there are 3 points given, which are:

(5, 3), which means 3 pages are edited every 5 mins

(10, 6), which means 6 pages are edited every 10 mins.

(15, 9), which means 9 pages are edited every 9 mins.

Pages edited per minute, using the point (10, 6) would be:

y/x = 6/10. This means ⁶/10 of a page is edited per minute

The correct statements that interprets the graph are:

✅6/10 of a page is edited per minute

✅3 pages are edited every 5 min

Veronica got 3 times as many gifts as Natalie. Together Veronica and Natalie got a total of 12 gifts how many gifts did Natalie
fenix001 [56]
The equation we'll use for this is:Total Gifts = Veronica's Gifts (v) + Natalie's Gifts (n).
12 = v + n
The problem says Veronica got 3 times as many gifts as Natalie.
You can directly translate this into an equation!
v = 3 * n = 3n.  This means we can replace any v with 3n.
So, 12 = v + n = 3n + n = 4n
12 = 4n
3 = n.  Natalie got 3 gifts.
We can now plug back in for Veronica's gifts:
v = 3n
v = 3(3)
v = 9.  Veronica got 9 gifts.

What are the steps for solving this equation, quick please, im in a zoom! -2(-2k+3)+4k=-2(6-3k)+2k
Katyanochek1 [597]

Answer:

0 = -6

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

−2(−2k+3)+4k=−2(6−3k)+2k

(−2)(−2k)+(−2)(3)+4k=(−2)(6)+(−2)(−3k)+2k(Distribute)

4k+−6+4k=−12+6k+2k

(4k+4k)+(−6)=(6k+2k)+(−12)(Combine Like Terms)

8k+−6=8k+−12

8k−6=8k−12

Step 2: Subtract 8k from both sides.

8k−6−8k=8k−12−8k

−6=−12

Step 3: Add 6 to both sides.

−6+6=−12+6

0=−6

A + (-25)=75 <br> Solve the equation
gogolik [260]
You can rewrite this as A - 25 = 75. You always can cancel adding a negative into just subtracting, and although it may not seem important yet, it’s a good habit to get into for further algebra.
A = 100.
