14 - ( 9t - 2 ) < - t + 30 Anyone know multistep equations

ZanzabumX [31]

Answer:

t > -7/4

Step-by-step explanation:

Step 1: Write out inequality

14 - (9t - 2) < -t + 30

Step 2: Distribute

14 - 9t + 2 < -t + 30

Step 3: Combine like terms

-9t + 16 < -t + 30

Step 4: Add 9t to both sides

16 < 8t + 30

Step 5: Subtract 30 on both sides

-14 < 8t

Step 6: Divide both sides by 8

-7/4 < t

Step 7: Rewrite

t > -7/4

Twenty-six students will attend the field trip to the career center. The cost to attend the career center is $x. Fifteen of thes

dexar [7]

Answer=I

15(x+3)+11x represents the total cost

To solve for this, let's look at the information that we know...

26 students go on the trip

15 students pay $3 more for an additional class (x+3)

26-15=11

11students pay, x, the price of the trip.

So 15(x+3) represents the 15 students who pay for both the trip and the automotive class, and 11x represents the students who simply just pay for the cost of the trip.

Thus, 15(x+3)+11x represents the scenario

Diane runs 10 miles in 55 minutes, how many minuets does she take per mile?

Brut [27]

Step-by-step explanation:

Hi!!

 It's simple, you can do it easily. 

no. of miles = 10 miles

time = 55 mins.

now,

no. of mins for 1 mile = no. of miles/ time

 = 10 /55

 =0.18181818 min.

so, she takes 0.181818 or 2/11 min per each mile.

Hope it helps...

A rectangle with an area of 47 m² is dilated by a factor of 7. What is the area of the dilated rectangle?

MA_775_DIABLO [31]

We already know that the area of the rectangle increased by a square of the factor 7. So the dilated area of it (which we will call "Ad"), is:

Ad= (47)(7^2)
Ad= 47x49
Ad= 2303 m^2

What is the area of the dilated rectangle? The area of the dilated rectangle is 2303 m^2.

Julio tested the point (4, –2) to see whether it is a solution to this system of equations. –3x – 2y = –8, y = 2x – 5 His work i

kolezko [41]

if it is solution point (4, –2) must satisfy both equations
(1) –3x – 2y = –8-->-3*4-2*(-2)=-8
-12+4=-8 then-->-8=-8 ok
(2) y = 2x – 5
-2=2*4-5=3---------->-2 is not 3

the point (4, –2) is not solution of the system of equations
