Jax has a weekly math test. His scores on the last 5 tests are 78,92,86,94,95. What score does he need to have an average of 90

lara [203]

Answer:

x = 95

Step-by-step explanation:

Given that,

Jax scores on the last 5 tests are 78,92,86,94,95.

We need to find the score he need to have an average of 90.

The formula for average of few number is given by :

Average = sum of observations/total no of observation

Let he score x in test 6. So,

$90=\dfrac{78+92+86+94+95+x}{6}\\\\90=\dfrac{445+x}{6}\\\\540=445+x\\\\x=95$

So, he must score 95 in the next test so that its average is 90.

2c+17.6 =6 / 4 SOLVE give your answer as a decimal get brainly

tamaranim1 [39]

Answer:

-8.05

Step-by-step explanation:

In order to solve for C you first have to subtract 17.6 from both sides.

2c=(6/4)-17.6

6/4 is 1.5

1.5-17.6=-16.1

2c=-16.1

c=-8.05

Solve the following equation: |-3x+3|-9=12

photoshop1234 [79]

Answer:

$\large\boxed{\left \{ {{x\: = \: 8} \atop {x\: =\: -6}} \right. }\\$

Step-by-step explanation:

$\left| -3x+3 \right| -9=12$

At first, let's add - 9 to both the sides. So,

$\left| -3x+3 \right| -9=12\\|-3x+3|=21$

Now, using the definition of absolute value, we can change the equation to..

$-3x+3=21 \\-3x+3=-21$

By, subtracting 3 from both the sides,

$-3x=18 \\-3x=-24$

Now, divide both the sides by 6,

$x=-6 \\x=8$

We now have 2 values of x. They are...

$\large\boxed{\left \{ {{x\: = \: 8} \atop {x\: =\: -6}} \right. }\\$
