5a - 10(3) = 45

Evaluate 10(3):

5a - 30 = 45

Add 30 to both sides:

5a = 75

Divide both sides by 5:

a = 15

Answer: a = 15

Simplify. (-2u?+u-3)+(4u²+7u+5)

Pavlova-9 [17]

Answer:

$2u^2+8u+2$

Step-by-step explanation:

$\left(-2u^2+u-3\right)+\left(4u^2+7u+5\right)$

$\blacksquare$ Remove parentheses:

$\longmapsto$ $-2u^2+u-3+4u^2+7u+5$

$\blacksquare$ Combine like terms:

$-2u^2+4u^2+u+7u-3+5$

$\longmapsto$ $-2u^2+4u^2=2u^2$

$\longmapsto$ $\:u+7u=8u$

$\longmapsto$ $-3+5=2$

$\leadsto$ $2u^2+8u+2$

Work out the percentage change when a price of £70 is decreased to £49

Monica [59]

Answer:

30% decrease in price

Step-by-step explanation:

Since 70-49=21, we know that the price decreased by 30 pounds. The formula to find a percentage decrease is that you should then divide the original number(70) by 21(that equals 0.3!) 0.3 as a percentage would then be 30%, so the answer is there is a 30% decrease in price.
