-3 = -3 (2t+1) t=? Step by step please

1 answer:

4 0

First you have to distribute the -3 to the 2t and the 1. That equals -6t and -3. Then, you have to make the -3 go to the other side that way you could leave the t alone. This means the -3 becomes a +3. -3+3=0 Next you have to divide the -6 with the zero that way the t is isolated (left alone). This equals 0. Which means that t=0.
Hope this helps!

<h3><u>The first number, x, is equal to 33.</u></h3><h3><u>The second number, y, is equal to 23.</u></h3><h3><u>The third number, z, is equal to 46.</u></h3>

x + y + z = 102

z = 2y

x = 10 + y

Because we have values of x and z, we can plug them into the original equation to solve for y.

10 + y + y + 2y = 102

Combine like terms.

4y + 10 = 102

Subtract 10 from both sides.

4y = 92

Divide both sides by 4.

y = 23

Now that we have a value for y, we can find the value of x and z.

z = 2(23)

z = 46

x = 10 + 23

x = 33

Distance =rate/time so your answer is 3 hours first you have to convert meters to kilometers 921000 meters = 921 Km so you have like terms to calculate so your distance becomes 921 Km then divide by the speed 907÷3 = 3 so your answer is 3 hrs

4(0.5f−0.25)=6+f what is f<br><br><br> I am so lost when we were doing this in class

muminat

4 (0.5f - 0.25) = 6 + f
2.0f - 1.0 = 6.0 + f
1.00f = 6.0 + f
f = -5.0
hope this is right,
