When you compare 649 and 645, you see that the first two digits are the same, and you compare until the last digit: in a way you need to do 3 comparisons, one for each digit (and after first and second you conclude that you still need to compare).

when you compare 645 and 738 you see immediately that the second number is bigger: the numbers differ already in the number of hundreds than they have, so you don't need to compare their tenths and one's, just the hundreds.

Solve and check 5(g - 5) - (5 - g) =12. show work

aleksandrvk [35]

$5 (g-5) - (5-g) = 12\\5g - 25 -5 +g =12\\6g -30 = 12\\6g = 42\\g = 7$

Check:

$5(7-5) - (5-7) = 5 (2) - (-2) = 10 + 2 = 12$

Find the values of the unknown constants for the identities

ankoles [38]

Answer:

a = 1 and b = - 10

Step-by-step explanation:

Expand the right side of the identity

x(ax² - 3x + b) - 3(ax² - 3x + b)

= ax³ - 3x² + bx - 3ax² + 9x - 3b

= ax³ - x²(3 + 3a) + x(b + 9) - 3b

Equate the coefficients of like terms on both sides of the identity

x³ terms → ax³ with x³ ⇒ a = 1

x terms → - x with (b + 9)x ⇒ b + 9 = - 1 ⇒ b = - 10

Find the HCF of terms and factorise: 20x3 – 40x2 + 80x

sergiy2304 [10]

Answer:

The largest factor that can be pulled out of that expression is 20x, giving you 20x(x² - 2x + 4)

Step-by-step explanation:

20x³ - 40x² + 80x

= 20x(x² - 2x + 4)

Put your answer as a reduced fraction.<br><br> Solve.<br><br> y/-8 = 1/16<br><br> y =

frozen [14]

Hey there!☺

$Answer:\boxed{y=\frac{-1}{2}}$

$Explanation:$

$\frac{y}{-8}=\frac{1}{16}$

In our first step, we will use the cross multiply method:

$\frac{y}{-8}=\frac{1}{16}\\ y*(16)=(1)*(-8)\\16y=-8$

In our second/last step, we will divide both sides by 16:

$\frac{16y}{16}=\frac{-8}{16}\\y=\frac{-1}{2}$

Hope this helps!☺
