Answer:

108 units

Step-by-step explanation:

We are given that

Length of each office,l=10 units

Breadth of each office=b=8 units

Total number of office=3

We know that

Perimeter of rectangle= $2(l+b)$

Using the formula

Length of cable for 1 office= $2(10+8)=36units$

Length of cable required for 3 offices= $36\times 3=108$ units

Hence, the required length of cable=108 units

When 0.3(4x – 8) – 0.5(–2.4x + 4) is simplified, what is the resulting expression?

Answer:

=2.4x-4.4

Step-by-step explanation:

did the test

0.3(4x-8)-0.5(-2.4x+4)

=1.2x-2.4-0.5(-2.4x+4)

=1.2x-2.4+1.2x-2

=2.4x-4.4

1) you can buy 6 candy bars because $5.10 / $0.85 =
6.
To check: 6*0.85=5.10

2) you can find the answer by adding 3 to 12. 3+12=15 n=15 and it said n can be greater than or equal so
N(greater than or equal to sign) 15.
To check: 15-3=12
12=12
16-3>12
13>12

7) x-7=12
+7 +7
X=19
To check: 19-7=12
12=12

8) y/8=7
*8 *8
Y= 56
To check: 56/8=7
7=7

9) 10-4x=6x
+4x +4x
10=10x
/10 /10
X=1
To check: 10-4(1)=6(1)
10-4=6
6=6

Hope this helped!

Add the fractions and simplify the answer 1/2 +2 /3

IrinaVladis [17]

What we are going to do is add $\frac{1}{2}$ by $\frac{2}{3}$ . The first thing we do is make common denominators for $\frac{1}{2}$ and $\frac{2}{3}$ : $\frac{1*3}{2*3}= \frac{3}{6} \ and \ \frac{2*2}{3*2}= \frac{4}{6}$ . Now we add $\frac{3}{6}$ by $\frac{4}{6}$ : $\frac{3}{6}+ \frac{4}{6}= \frac{7}{6}$ . Now we make $\frac{7}{6}$ a mixed number: $\frac{7}{6}=1 \frac{1}{6}$ . Therefore, your answer is $\boxed{\boxed{1 \frac{1}{6}}}$ . Hoped I helped. :)
