Answer:
Step-by-step explanation:
So the sign means that y has to be less than or equal to x plus 9
if you wanted an answer an example could be
y = 1
x = 10
this works because if implemented into the equation
1 ≤ 10 + 9 which is true
Answer:
Step-by-step explanation:
FE=4+4=8
Altitude=3+3=6
area=1/2×FE×6=1/2×8×6=24 sq. units.
or
area=1/2×
I 1 3|
|-4 -3|
| 4 -3|
| 1 3|
=1/2[(-3+12)+(12+12)+(12+3)]
=1/2[9+24+15]
=1/2[48]
=24 sq. units
Answer:
Step-by-step explanation:
Let
x ----> the measure of one angle of the triangle
y ---> the measure of the second angle
z ----> the measure of the third angle
we know that
The sum of the measure of the interior angles in any triangle must be equal to 180 degrees
-----> equation A
One angle of a triangle measures 10 degrees more than the second
----> equation B
The measure of the third angle is twice the sum of the first two angles
---> equation C
substitute equation B in equation C
----> equation D
substitute equation D and equation B in equation A
solve for y
Find the value of x
Find the value of z
therefore
Answer:
x = 11; z = 16
Step-by-step explanation:
9x- 35 = 5x+ 9
4x- 35 = 9
4x = 44
x = 11
180 - 64
Subtract 59.99 from 64.19.
64.19 - 59.99 = 4.20
<u>The tax she paid was $4.20, so now we need to find the percentage.</u>
Divide 4.20 by 59.99.
4.20 ÷ 59.99 = 0.07
Multiply 0.07 by 100 to find the percentage.
0.07 × 100 = 7
<u>The sales tax in the area was 7%.</u>
