Answer:
1. 8/3
2. 1/7
3. 1/12
4. 1/27
Step-by-step explanation:
1. 3/8 * m = 1
Multiply by 8/3
8/3 * 3/8 m = 1* 8/3
m = 8/3
2. 7 * m = 1
Divide by 7
7*m /7 = 1/7
m = 1/7
3. 3 ÷m = 36
Multiply by m
3 ÷m * m = 36*m
3 = 36*m
Divide by 36
3/36 = 36*m/26
1/12 = m
4. 4/9 ÷m = 12
Multiply by m
4/9 ÷m * m = 12*m
4/9 = 12*m
Multiply by 1/12
4/9 *1/12 = 12*m * 1/12
4/12 *1/9 = m
1/3*1/9 =m
1/27
Answer:
The two numbers are 36 (62) and 49 (72).
Step-by-step explanation:
PRQ and QRS should add to PRS
(3x-8)+(2x+6)=98
5x-2=98
5x=100
x=20
Plug 20 into both expressions:
3(20)-8
60-8
52 degrees= PRQ. <===========
2(20)+6
40+6
46 degrees= QRS. <==========
