1,4(0,5x + 4,2y) - 3,5(0,2x - 1,5y)
1,4.0,5x + 1,4.4,2y - 3,5.0,2x + 3,5.1,5y
0,7x + 5,88y - 0,7x + 5,25y
0,7x - 0,7x + 5,88y + 5,25y
11,13y
9 + √2 / 4 - √7
Multiply the numerator and denominator by the conjugate.
Exact form:
(36 + 9√ 7 + 4√2 + √14) / 9
or
about 7.69

Answer:
-5
Step-by-step explanation:
because it is less than -4 when it is suppose to be more than-4
the blue dot is at -11 value on the number line.
1. The red one
2. 60%
3. 18,57%
I use the way to calculate the percentage in question 2 and 3
2. (6:10)x100%
3. (13:7)x100%
= (100)^3(1/4)^3
= 15,625 i think im not that good at math but i passed
