let those numbers be x and y
According to your question
x + y = -7
x - y =14
adding both equations
2x = 7
or x = 7/2
substitute value of x in either equation
y = -21/2
So,
x= 7/2
y=-21/2
Hope this helps!
Thanks
An equivalent form of the compound inequality −22 > −5x − 7 ≥ −33 will be −5x − 7 > −22 and −5x − 7 ≥ −33
<h3>Compound inequality</h3>
A compound inequality (or combined inequality ) is two or more inequalities joined together with inequality operations.
Given the compound inequality −22 > −5x − 7 ≥ −33, this can also be splitted into;
−22 > −5x − 7 and −5x − 7 ≥ −33,
The inequality expression −22 > −5x − 7 is also expressed as −5x − 7 > -22. Hence an equivalent form of the compound inequality −22 > −5x − 7 ≥ −33 will be −5x − 7 > −22 and −5x − 7 ≥ −33

6% of her $37,000 in sales: 37,000 x 0.06 = 2220
Salary $1,800 + $2,220 (commission) = $4,020
So her total earnings: $4,020
Answer:
x = 10
Step-by-step explanation:
Since the triangle is right use the sine ratio to find x
sin30° = 
= 
cross- multiply
x × sin30° = 5 ( sin30° = 0.5 )
0.5x = 5 ( divide both sides by 0.5 )
x = 10
Answer:
Step-by-step explanation:
it's kinda confusing b/c of the minus signs.. huh... but -5 is less than -2 sooo
start with
-2 1/2 - (-5 3/4 )
=5 3/4 - 2 1/2
=5 3/4 - 2 2/4
=23/4 - 10/4
=13/4
there you go... :)
if you want it back in proper fractions
3 1/4
