Answer:
-14
Step-by-step explanation:
Plug 3 in for x
-2 (3)² + 3 + 1
-2 (9) + 3 + 1
-18 + 3 + 1
-14
She needs 8 more dollars.
if you multiply 3 times 5 equals 15
and 4 times 3 equals 12
then add that which is 27
35 minus 27 is 8.
I will say it is 8/4 if you simplified 8/4 by 4 it will be 2/1.
23) It is right angle triangle, so the sum of acute angle must be equal to 90
sum of ratio units = 2+7 = 9
value of 1 unit = 90/9 = 10
measures of angle would be 2(10) & 7(10) = 20 & 70
Measure of smaller angle is 20
24) It is only graphical work. You have to do it on your own cause I can't show you here, sorry!!
If Fraction has denominators such as 10, 100 or 1000 it would be easy to convert it into decimal. Like this:
6
------- - Fraction.
100
Now, Write down the number six and add zeros to it. If the denominator has 2 zeros in it then the there should be two decimal numbers. Answer for the above fraction would be: 0.06.
If a fraction does not have denominators such as 10, 100 or 1000, then do the following:
6
------
25
The above fraction's denominator is not 10, 100 or 100. So, multiply the numerator and the denominator with a number that would give you the denominator as 10, 100 or 1000.
6 × 4 = 24
----- ---- -------
25 × 4 = 100
Now, you can convert it as 0.24
If a fraction has a denominator that cannot be converted into 10, 100 or 1000, then directly divide and write the decimal.
Hope it helped you, Sophia46!!
