Solve for u -2/9u=10

Nata [24]

Answer:

$u = -45$

Step-by-step explanation:

<u>Step 1: Multiply both sides by -9/2</u>

<u /> $-\frac{2}{9}u = 10$

$-\frac{9}{2} *-\frac{2}{9}u = 10 * -\frac{9}{2}$

$u = -\frac{90}{2}$

$u = -45$

Jay estimates that a basketball weights about .5 pounds. Shawna estimates that a basketball weights about.05. Whose estimate is

Natasha_Volkova [10]

Answer:

Jay's estimate is closer to the actual weight of the basketball

Step-by-step explanation:

The standard weight of an NBA basketball is 1.4 pounds.

Judging the accuracy of Jay's and Shawna's answer based on their percentage error when compared with the standard, we have that Jay's answer has a lower error as shown below

Error = (Standard value - Estimated value)/ Standard Value ×100

Error in Jays answer = $\frac{1.4 - 0.5}{1.4}$ × 100 = 64.28 %

Error in Shawna's answer = $\frac{1.4 - 0.05}{1.4}$ × 100 = 96.42%

From this, It is obvious that Jay's answer has a lower percentage error when compared to the actual value.

Congratulations! You just won the lottery and plan to buy a bunch of cars and motorcycles for all your friends. You purchase 50

Sedaia [141]

Step 1

Let n represent car and m represent motorcycles.

n + m = 50 ...................1

car has four wheels and motorcycle has two wheels

4n + 2m = 164 .............................. 2

Step 2

Solve equation 1 and 2 simultaneously.

from (1), make n subject of relation and substitute in equation 2.

n = 50 - m

Step 3

Substitute n in equation 2

4(50 - m) + 2m = 164

200 - 4m + 2m = 164

collect like terms

200 - 164 = 4m - 2m

36 = 2m

m = 36/2

m = 18

next find n

n = 50 - m

n = 50 - 18

n = 32

There are 32 cars and 18 motorcycles.
