Brenda received 3 times as many grades as Robert. Timothy received half as many 85s as Brenda. How many grades of 85 did Brenda,

Diano4ka-milaya [45]

Answer:

11 grades of 85 did Brenda, Robert, and Timothy receive altogether.

Step-by-step explanation:

Let 6x be the number of 85 received by Brenda.

The number of 85 received by Robert is 1/3 of Brenda= 2x

The number of 85 received by Timothy is 1/2 of Brenda= 3x

Then according to the given conditions

6x+ 2x+ 3x

= 11x

So the number of total 85s received by all the three is 11.

11 grades of 85 did Brenda, Robert, and Timothy receive altogether.

If AC=18x-7,find the x. Round to the nearest hundredth if necessary <br>AB=7x+29 <br>BC=30

Margaret [11]

Answer:

$x=6$

Step-by-step explanation:

AC = AB + BC

$18x-7=(7x+29)+30$

$18x-7=7x+29+30$

$18x-7=7x+59$

Add 7 to both sides:

$18x-7+7=7x+59+7$

$18x=7x+66$

Subtract 7x from both sides:

$11x=66$

Divide both sides by 11:

$\frac{11x}{11}=\frac{66}{11}$

$x=6$
