Hope this is what you wanted!
Alexandera=a
imani=i
a is 8 more than i or
a=8+i
the sum of the 2 numbers is 50 or
a+i=50
a=8+i
so subsitute 8+i for a in a+i=50
8+i+i=50
8+2i=50
subtract 8 from both sides
2i=42
divide both sides by 2
i=21
subsiutte into a=8+i
a=8+21
a=29
a=29
i=21
Answer:
19
Step-by-step explanation:
<em>1</em><em>3</em><em>×</em><em>3</em><em>=</em><em> </em><em>3</em><em>9</em>
<em>1</em><em>4</em><em>.</em><em>5</em><em>×</em><em>4</em><em>=</em><em> </em><em>5</em><em>8</em>
<em>5</em><em>8</em><em>-</em><em>3</em><em>9</em><em>=</em><em> </em><em>1</em><em>9</em>
Answer:
No.
Step-by-step explanation:
If something is <em>less</em> than 5, no, however if something is less than or equal to (≤ sign), then yes.
To solve this problem, we are going to use the percent proportion, a/b = p/100, where a is the part of a number b, the whole, and p is the percentage out of 100.
When we fill in our known integers into this equation, we get
21.12 / b = 25.6 / 100
Next, to simplify this equation, we should use cross products (means - extremes products theorem). This means multiplying the numerator of one fraction and the denominator of the other fraction and setting them equal to one another.
21.12(100)=25.6(b)
When we multiply, you get
2112 = 25.6b
Finally, we divide both sides by 25.6, to get our variable b, alone, and without a coefficient.
82.5 = b
Therefore, 25.6% of the number 82.5 is 21.12.
