Answer:

5:40

explanation:

The hour hand(the short hand) is on 5. The minute hand(the long hand) is on the 1 meaning 5 minutes have passed. The time on the clock says 5:05. If we add 35 minutes to that we get 5:40.

Given: y=x^3 and y=343
So, 343=x^3
Cube root both sides which will get rid of the cube on the right side of the equation
You are left with the cube root of 343. Which equals 7.
7*7*7=343
X=7

The partial factorization of x2 – x – 12 is modeled with algebra tiles.

garik1379 [7]

Answer:

x² – x – 12 = (x – 4)(x + 3)

Step-by-step explanation:

Identify two numbers that add to -1 and multiply to -12, let's call them p and q.

So ax² + bx + c = (x + p)(x + q)

pq = c

p + q = b.

It is easier to find these numbers by finding factors of -12.

This can be done by splitting the number up until all the numbers are prime.

-12 → 6 × -2 or -6 × 2 → -(3 × 2 × 2)

There can only be two numbers so the only options we have are 6 and -2, -6 and 2, 3, and -4, or -3 and 4.

We can eliminate them by adding them up.

6 + -2 = 4 ≠ -1 so that can't be it.

-6 + 2 = -4 ≠ -1 so that can't be it either.

-3 + 4 = 1 ≠ -1

therefore p and q are 3 and -4 because 3 + -4 = -1.

so x² – x – 12 = (x – 4)(x + 3)

p = -4, and q = 3.

(x – 4)(x + 3) = x(x + 3) – 4(x + 3) = x² + 3x – 4x + 12 = x² – x – 12

write a equation 2 solve for x you are only writing the equation they said it was wrong 8x+10 12x -18 or did i do it backwards d

andrezito [222]

Answer:

x=1.25

Step-by-step explanation:

8x+10=12x-18-10=7

8x+12x=10-18+10+7

20x=25

d.b.s by 20

20x/20=25/20

1=1.25 

I thinks I am right if not pls reply me with the correct answer pls

x=1.25
