AB = 4 x - 9
BC = 3 x + 5
AC = 7

B is in between A and C.  <u>So AB + BC = AC</u>

4x - 9 + 3 x + 5  =  7
7 x - 4 = 7              take -4 from LHS to the R H S (right hand side) it becomes +4
7 x = 7 + 4  = 11
x = 11/7    = 1.571

12% of birr x is 840,what is the value of x​
Diano4ka-milaya [45]

The value of x will be 7000 for the expression 12 % x = 840.

We are given a number x.

We are also given as 12 % of x is 840

writing it in the form of an expression, we get that:

12 % x = 840

12 / 100 × x = 840

12 x = 84,000

Dividing both sides by 12, we get that:

12 x / 12 = 84,000 / 12

x = 7000

Therefore, the value of x will be 7000.

The volume of an oblique pyramid with a square base is V units3 and the height is h units. Which expression represents the area
givi [52]

Answer:

Area of the base of the pyramid = V/h

Step-by-step explanation:

Mathematically, we know that the volume of the pyramid can be calculated by multiplying the area of the base by the height of the pyramid

Now using the variables in the question;

V = area of base * height of pyramid

Area of base = V/height of pyramid

Area of base = V/h

WILL MARK BRAINLIEST CAR!!!! HELP
Digiron [165]

Answer:

111°

Step-by-step explanation:

Let the centre of the circle be C

mRQ=157 (marked)

The angle at the centre of a circle standing on an arc is twice any angle at the circumference, standing on the same arc. So <SCR=2(SQR)=2(46)=92. mSR=<SCR=92

All the arc measure add up to 360 so:

mSQ+mRQ+mSR=360

mSQ+157+92=360

mSQ=360-249=111
