Answer:
X= 1/2 Y= 5
Step-by-step explanation:
8x+7y=39-------------(1)--------×2
4x-14y= -68-----------(2)-------×1
16X + 14Y = 78--------(3)
4X- 14Y = -68----------(4)
Addy equation (4) and (3)
20X = 10
dividing bothsides by 20
20X/20= 10/20
X = 1/2
substitute the value of X into equation (1)
8X+7Y = 39
8(1/2)+7Y= 39
4+7Y = 39
7Y = 39-4
7Y = 35
dividing bothsides 7
7Y= 35/7
Y = 5
-10×-10= 100×-10= -1,000
p^12= p^4
q^3= q
-10p^4q
hope this helps!
The first one is distributive property
I think the 2nd and last are associative
and the last is commutative
Step-by-step explanation:
Water makes up more than half of our body weight. Without water, all organisms in the world would die. Water is necessary not only for drinking but also for our day to day life purposes like bathing, cooking, cleaning, and washing and so on. We cannot imagine a life without water.
Answer:166.7 milliliters
Step-by-step explanation:
height(h)=13cm
Radius(r)=diameter ➗ 2
r=7 ➗ 2
r=3.5cm
π=3.14
Volume=(π x r^2 x h) ➗ 3
Volume=(3.14 x (3.5)^2 x 13) ➗ 3
Volume=(3.14x3.5x3.5x13) ➗ 3
Volume=500.045 ➗ 3
Volume=166.7cm^3
1 cm^3=1mL
Therefore 166.7cm^3=166.7mL
