how do I solve this
t + 1 = -3

Answers

Solve for t. Simply sense its +1, do the opposite and minus 1 from both sides of the equation. +1 - 1 = 0; -3 -1 = -4. Therefore, t = -4 is the correct solution.

Answer:

-4

Step-by-step explanation:

"t" could be any number.

The equation is basically asking, if you add 1 to a number, and it equals -3, then what number did you add to? To solve this just reverse the equation (subtract 1 from -3), which will get you -4.

"t" is -4

The rectangular front yard of a house has a length to width ratio of 4:5. If the perimeter of the yard is 90 meters, what is the length of the yard

A. 50 meters
B. 40 meters
C. 25 meters
D. 20 meters

Answers

Answer:

B!

Step-by-step explanation:

If the ratio is 4:5, then that means you can take the 90 and divide it by 9 (4+5) which is 10. You now know that each unit in the ratio is equal to 10 meters. If the length is 4 units, take that 4 and multiply it by 10.

Declan has n baseball cards. Sam has 4 times as many baseball cards as Declan. Amaya has 7 fewer baseball cards than Sam. Which expression represents the number of baseball cards that Amaya has?

Answers

Answer:

4n-7

Step-by-step explanation:

First, you know that Sam's equation is 4n, since it is 4 times Declan's value n. Next, you take Sam's equation and subtract 7 from that value, since Amaya has 7 fewer cards than Sam. The final equation will be 4n-7.

Okay I get it now, N is equal to 4-7.
