Let’s call the tree in which is growing at a rate of 1 foot per year Tree A, and the tree growing 0.5 feet a year Tree B. In 2 years Tree A will be 7 feet high. Tree B, in two years will be 7 feet, because .5 x 2 is equal to 1 foot. Therefore making Tree B 7 feet.

ANSWER:
In two years Tree A (1 foot per year), and Tree B (0.5 feet per year) will grow to 7 feet.

Hope this helped. Have a great day. And a thank you or brainliest is very appreciated.

Twice the difference of a number + -3 is 4 find the number
NNADVOKAT [17]

Answer:

The number is 5

Step-by-step explanation:

If we need to find the hidden number, Which for simplicity's sake we will denote as "n", lets first write out the equation.

"2 x [n + (-3)] = 4"

We can work through this problem backwards. if we need two times the sum of "n" and (-3) to get to 4, the only number that can be multiplied by 2 to get a product of 4 is 2, so "n" + (-3) must equal 2. so, From here, we can figure out that since 5 + (-3) equals 2, "n" Must equal 5. so, if we plug in 5 for "n" the equation looks like this:

"2 x [5 + (-3)] = 4"

So, since the equation makes sense, the answer is, "n = 5"

Here's how to solve this problem.

Let  <span>x = number of mystery books on the shelf </span>
<span>Let 3x = total number of books on the shelf </span>

<span>we are told that </span>
<span>x/5<10<x/4 </span>
<span>multiply by 20, </span>
<span>4x<200<5x </span>
