C=27
3.) B
4y-10=22
+10 +10
4y=32
/4 /4
Y=8
4.)$132
60r+0.06(50r)=p
60(4)+0.06(50*4)=p
120+12=p
132=p
5.) $9.40
7+0.012(10,000-8,000)
7+0.0012(2,000)
7+2.4
9.4
Answer:
5(x+8)
Step-by-step explanation:
To factorise
5x+40
The value common to the two is 5
5(x+8)
The final answer is
5(x+8)
Percent means part out o 100
30.75%=30.75/100=3.075/10=0.3075/1=0.3075
thousandth is 3rd place
for 0.1234, thousandth would be the 3
to round to thousandth, look one place to the right (to the 4), if that number is:
greater than or equal to 5, add 1 to the thousandth place (3 turns to 4)
less than or equal to 5, leave the thousandth place as is (3)
so
0.3075
7 is thousandths
5 is before it and is equal to or greater to 5
7+1=8
