Answer:

Given the equation:  d = \frac{LM}{R_2+R_1}      .....[1]

Cross multiply states that an equation of fractions when each of the side consists of a fraction with a single denominator by multiplying the numerator of each side by the denominator of the other side and equating these two products obtained.

Apply the cross multiply in [1], we get;

d(R_2 +R_1) = LM

Divide both sides by M  we get;

L = \frac{d(R_2+R_1)}{M}

or

L = \frac{dR_2+dR_1}{M}

A two digit number divided by another two digit number,we get 3.675 what are the numbers?​
Over [174]

Answer:

Step-by-step explanation:

I can't get the exact answer you've given, but I can tell you some things about it. The largest number in the denominator is 30 or 31. That's because 31 * 3 is 93 exactly. However the fraction is a problem and will likely push you over 100.

3.675 * 31 = 113 something. So 31 is too big.

The closes I came was 98 / 26 which is 3.769

T is the midpoint of S and U. ST=7x+4 &amp; TU=10x-2. What is the value of SU?
wariber [46]

Answer:

SU = 36

Step-by-step explanation:

T is the mid point so the distance of ST and TU is the same. Since ST and TU are the same, 7x + 4 = 10x - 2.

Solve for x

7x + 4 = 10x - 2

7x - 10x = - 2 - 4

-3x = -6

x = 2.

Find SU

SU = ST + TU

= (7x + 4) + (10x - 2)

substitute the value for x into the equation (x=2)

[7(2) + 4] + [10(2) - 2] = 36

I hope this helps :)

How many band uniforms can be made with 131 3/4 yards of fabric if each uniform requires 3 7/8 yards
ElenaW [278]
The question can be read as how many 3 \frac{7}{8} can be made out of 131 \frac{3}{4}

131 \frac{3}{4}÷3 \frac{7}{8} ⇒ We need to change each mixed number into an improper fraction

131 \frac{3}{4}= \frac{[131*4]+3}{4}= \frac{527}{4}
3 \frac{7}{8}= \frac{[3*8]+7}{8}  = \frac{31}{8}

\frac{527}{4}÷\frac{31}{8}
\frac{527}{4}×\frac{8}{31}
\frac{527*8}{4*31}= \frac{4216}{248} =17

Answer: 17 uniform
