Mathematics
1 answer:
Svetach [21]3 years ago
6 0

Answer: ≥ without the line on the bottom.

Step-by-step explanation:

I am assuming the expression you are talking about are

3w^{2} +1 and 10w+8.

If we were to replace w with 4 and calculate, we will find the answer:

3*4^{2}  +1=3*16+1=48+1=49

10*4+8=40+8=48

Since the first expression, 3w^{2} +1, is bigger than the second expression, the correct symbol to use is ≥ without the line on the bottom.

zysi [14]
A triangle with a base of 2 and a height of 3.

Double the base and it becomes 4, and double the height and it becomes 6.

Area of the new figure = 1/2 * base * height = 1/2 * 4 * 6 = 2 * 6 = 12

The area of a towelette with double the base and double the height is 12 inches^2.

jack ran 1.5 kilometers on the treadmill, then walked 475 meters before running another 2.5 kilometers how many kilometers did j
qaws [65]
We need first consider what data we have available:
a = run 1.5km
b = then run 2.3km
c = walk 475m
x = a + b + c = how many km he done on treadmill
before we go anywhere, we need to unify the units, we need to change meters to fraction of kilometers, kilo meant 1000, therefore:
1km = 1000m
475m / 1000m = 0.475km
now we can substitute:
x = a + b + c = 1.5km + 2.3km + 0.475km = 4.275km
we can round that up to first decimal point and then:
4.275km = 4.3km
answer is then:
jack done on the treadmill 4.275km or rounded up 4.3km

5+(×-2)=-8 need help with answer​
Jet001 [13]

Answer:

5 + x + (-2) = - 8 simplifies to:

x + 3 = - 8

Subtract 3 from both sides to get variables on one side of the equal sign and constants on the other.

x = - 8 - 3

x = - 11
