Answer:

x=4

Step-by-step explanation:

It suffices to equate any two sides and then check whether the solution is valid for the third side.

Taking 2x and 3x-4 and equating:

2x = 3x-4

x = 4

This means the sides are both of length 8. Now check whether for x=4 the third side is also of length 8:

x+4=4+4=8

which indeed works out confirming x=4 being a valid solution

A peqch pie is made with 13 peaches, which are evenly distributed throughout the pie. If Joe ate one slice that contained exactl
bekas [8.4K]

Answer:

138.5°

Step-by-step explanation:

Since the peach pie is a circle, we have a total angle of 360°.

We need to determine what fraction of the total pie of 13 peaches is the 5 peaches contained in Joe's slice.

This is number of peaches in Joe's slice/total number of peaches in pie = 5/13. To find the angle Joe's slice measures, we multiply 5/13 by 360°.

So, 5/13 × 360°

= 0.3846 × 360°

= 138.46°

≅ 138.5° to the nearest tenth of a degree

(1/8 + 3/12) x (1 1/6-1/2)
aivan3 [116]

Answer:

1/2

Step-by-step explanation:

(1/8+3/12)×(11/6-1/2)

Using bodmas

Deal with the bracket first and it should start with the addition

1/8+3/12

Lcm of the two is 96

12+24/96

=36/96

Then move to the next bracket

11/6-1/2

Lcm is 6

11-3/6

=8/6

Bring the two answers together

36/96×8/6

=1/2
