Answer:
C, E, and F
Explanation:
There are two ways to answer this question. First, you could simply input each answer into both equations to see which one works but that would take quite a long time.
A better way is to simply solve each equation for x.
You could rewrite
2x + 7 < -3
as
2x + 7 = -3
and solve:
Subtract 7 from both sides
Now divide both sides by 2
Now we can simply replace the equals sign with the inequality
x < -5
Where you can run into trouble is if you have to multiply or divide by a negative number across the equation, you must flip the inequality sign. It's best to leave it there to remind you, but I switched it out just to show that it's no different than a typical algebraic equation.
Now, we know that x can be any value less than -5. Let's find out the same thing for the second equation:
Now we know that x must be less than 1 for the second equation. So, now we can choose the answers that are both less than -5 and less than 1.
These answers are:
C. -10
E. -8.24
and
F. -15/2 which is -7.5
NOTE: -5 is equal to but not less than -5 so G is not included.
Decimal: .25
Fraction: 2/4, 3/6, 4/8, 5/10, and so on.

<span>if a triangle is a right triangle, the square of the longest side will equal the sum of the squares of the other two sides:
(3√2)² = 3² + 3²
18 = 9+9
18 = 18
The triangle is a right triangle. </span>
Answer:
or 18.4
Step-by-step explanation:
lets let x=4
4*4+(4*3/5)
4*4+12/5
16+12/5
16+2.4
answer... 18.4
