3x-4y=10
-20-x+2y=10 then -30+2y=x now plug this in the other equation:
3(-30+2y)-4y=10
-90+6y-4y=10
2y=100
y=50
Answer:
35/4
Step-by-step explanation:
- 8 × 4 = 32
- 32 + 3 = 35
- Write 35 over the original denominator: 35/4
I hope this helps!
X^1/2 ( x + 3) (x - 6)
= x^1/2 ( x^2 - 3x - 18)
= x^5/2 - 3x^3/2 - 18x^1/2
= (sqrt x)^5 - 3 (sqrt x)^3 - 18x^1/2
Option 1
Answer:
Vector is 32 years old.
Step-by-step explanation:
As it is given that Mags is 34 years old and he is 2 years older than Vector.
Since Mags is 2 years older than Vector, Vector's age is 2 year less than Mags.
therefore we subtract 2 years from the age of Mags.
= 34 - 2 = 32 years
So Vector is 32 years old.
Answer:
Step-by-step explanation:
1.
19² = 17² +x²
19² - 17² = x²
√361-289 =x
√72 = 8.5 ≈ x
Area = base*h/2 = 17*8.5/2 ≈ 72.3
Perimeter = 19+17+8.5= 44.5
and so on...
2.
x²= 5² +13²...
A= 5*13/2 =...
P= 5+13+x=...
3.
20² = 10² +x²...
A=10*x/2=...
P=20+10+x=...
4.
x² = 5² +14²...
A=5*14/2 =...
P= 5+14+x = ...
