3-(x+1)=3-x-1

(+3)-(x+1)

(+3)-1(x+1)

Distribute the -1 to (x+1)

(+3)-1x-1

3-x-1

-x+2

3-1(x+1) = 3-x-1

Step 1. distribute the negative sign

2(-x-1) = 3-x-1

Step 2. distribute the 3

-2x-3= 3-x-1

add 3 on both sides

-2x = 6 - x - 1

add x to both sides

-1x = 6 - 1

-1x=5

x=5

SO..... u have to plug 5 in

To find the height of the peak, list the corresponding sides and angles of the two triangles you and Tyler have created. (6 poin
sukhopar [10]
We know that

Right triangles PBM and MTF are similar 
because
angle PMB=angle TMF
and
angle BPM=angle FTM
and 
angle B =angle F=90 degrees
so
corresponding sides are
BM and MF
PB and TF
PM and MT
(PB/TF)=BM/MF
solve for PB
PB=(TF*BM)/MF
where
TF=6ft
BM=20 ft
MF=3 ft
so
PB=(6*20)/3------> 40 ft

the answer is
<span>the height of the peak is 40 ft</span>

Seth's mother brought home 3/4 of a chocolate cake and 1/2 of a vanilla cake that was left from a party at her work. Seth ate 1/
Oduvanchick [21]

Answer:

1/4 of the cake.

Step-by-step explanation:

Since he ate 1/3 of 3/4 of the chocolate cake, we will need to multiply fractions to solve this.

\frac{3}{4} * \frac{1}{3} =  \frac{3}{12}  = \frac{1}{4}

Therefore, he ate 1/4 of the entire cake.
