You solve the equation for x. First, subtract 7 from both sides.Then subtract 3x from both sides. Then you should get 2x = 16. Divide both sides by two, and you will get x=8.

In Circle M, points A, B, and C are located on the circle such that measure angle CBM equals to 34 degrees. What represents angl

Bess [88]

Answer:

Angle CAB=56 degrees

Step-by-step explanation:

See the attached image for the diagram.

In triangle BMC

|BM|=|MC| (Radii of a Circle)

Therefore, triangle BMC is an Isosceles Triangle; and

$\angle CBM=\angle BCM=34^\circ$

$\angle CBM+\angle BCM+\angle BMC=180^\circ$ (sum of \angle s$ in a triangle)\\34^\circ+34^\circ+\angle BMC=180^\circ\\\angle BMC=180^\circ-68^\circ=112^\circ$

Next,

$\angle BMC=2\angle CAB $(Angle at center is twice angle at circumference)\\112^\circ=2\angle CAB\\\angle CAB=112^\circ \div 2\\\angle CAB=56^\circ$

Barry is building a fence around rround his bacyard. The backyard is in the shape of a rectangle and the longest side of the yar

STatiana [176]

Answer:

10m

Step-by-step explanation:

Recall that the perimeter of a rectangle

= (2 x Long Side) + (2 x Short Side)

we are given that each of the long side = 20m and the perimeter is 60m

substituting these into the equation,

60 = (2 x 20) + (2 x Short Side)

60 = 40 + (2 x Short Side) (subtract 40 from both sides)

60-40 = (2 x Short Side)

(2 x Short Side) = 20 (divide both sides by 2)

Short Side = 20 / 2 = 10m

Instructions: Given one form of a sequence, write the other form.

Rufina [12.5K]

Answer:

The explicit formula is 15 + (n-1) -4

Step-by-step explanation:

The formula for an explicit formula is an = First number of the sequence (15) + (n-1)(times the amount of integers separating two different sequential numbers) which is -4.

For instance, since 15 is the first number, it will be a1 or 15. Next will be + (n-1) which is the same for every explicit sequence and the multiplier will be the difference between each number, which is -4 in the recursive sequence. As a result, the answer is 15 + (n-1) -4.
