Answer :

15x²

Step-by-step explanation:

$30x^{2}=2\times \left( 15x^{2}\right) \\45x^{5}=3x^{3}\times \left( 15x^{2}\right)$

Then the greatest common factor is 15x²

Answer:

To find GCF we need to find what these expressions have in common

30x²=5*3*2x²

45x⁵=5*3*3x²x³

Now we can see, that GCF=5*3*x² = 15x²

Ashley and Gabby bought lunch from the food trucks on Sugar Day. Ashley bought 3 tacos and a drink for $7. Gabby bought 2 drinks

kramer

Answer:

$1.5

Step-by-step explanation:

This would be solved using a simultaneous equation

let tacos = t

drink = d

3t + d = 7 -- eqn 1

2t + 2d = 8 -- eqn 2

Multiply equation 1 by 2 to derive equation 3

6t + 2d = 14 eqn 3

Substract equation 2 from equation 3

6t + 2d = 14 -- eqn 3

2t + 2d = 8 -- eqn 2

= 4t = 6

solve for t

6/4 = 1.5

= $1.5

Surface Area of a sphere, A grapefruit with C = 14cm.

9966 [12]

Surface area SA: $4\pi r^2$
Circumference C: $2\pi r$ dividing this you get $7=\pi r$ and $r= \frac{7}{\pi}$

Now let's input the radius $r$ into the Surface area formula...
$4\pi r^2\rightarrow 4\pi(\frac{7}{\pi})^2=4\pi(\frac{49}{\pi^2})=\frac{196}{\pi}$

Can u please help I need the answer to this equation

snow_lady [41]

Answer:

17°

Step-by-step explanation:

ΔXWZ = ΔYWZ (they are congruent triangles so ∠XWZ = ∠YWZ)

5x - 8 = 9x - 28

Rearrange and collect the like terms

-8 + 28 = 9x - 5x

20 = 4x

x = 5°

∠YWZ = 9x - 28

sub x = 5

= 45 - 28

= 17°
