The tot weight of a truck and its load is w pounds. Let /be the weight of the load . When it's empty the truck weighs 2,439 pounds. In this equation tells how to find w when you know /?

Therefore, when you know x, just substitute x into the equation, we can find out w.

w = x + 2,439

Step-by-step explanation:

Allow me to revise your question:

The total weight of a truck and its load is w pounds. Let x be the weight of the load . When it's empty the truck weighs 2,439 pounds. In this equation tells how to find w when you know x?

My

Given:

w is the total weight of a truck and its loadLet x is the weight of the load

We know that when it's empty the truck weighs 2,439 pounds, it means the weight of a truck is 2,439 pounds.

So we can form the equation:

w = x + 2,439

Therefore, when you know x, just substitute x into the above equation, we can find out w.

For example, we know x = 2,000 pounds, so the total weight (w) is:

w = 2,000 + 2,439 = 4,439 pounds.

Hope it will find you well

step-by-step explanation:

always plug in x. in this case, x equals 4.

i'm going to first solve 4(2+3x)

1) 4(2+3(4)) use pemdas to solve.

i'm going to multiply whats in the parenthesis first, so 3 times 4=12.

2)4 (2+12) i'm then going to multiply 4 by both numbers in the parenthesis (because multiplying comes before adding)

4 times 2= 8.   4 times 12= 48

4) (8+48)= 56 (answer)

i'm then going to solve 8+12x and plug in 4 for x.

1) 8 +12(4)

multiplying comes before adding, so i'm gonna multiply 12 and 4.

12 times 4= 48.

2) 8+48=56

both equal the same!

Your answer would be ahere is how: perimeter is how long all the sides are. in a rectangle, there are two sets of parallel sides. so, to find this, we would to the following.(15x2)+(4x2)30+838if you have questions ask! and mark me brainliest! i really wanna level up : 3
