Answer:
4+2b=5+5b+20
<=> -3b=21
<=> b=-7
Step-by-step explanation:
<=> 4+2b=5+5b+5×4
<=> 4+2b=5+5b+20
<=> 2b-5b=5-4+20
<=> -3b=21
<=> b=-21/3
<=> b=-7
Answer:
3/68
Step-by-step explanation:
probability of blue = 4/17
after blue is selected, total number decreases by 1
so, probability of green = no fo greens/total number = 3/16
so probabilty = 4/17 * 3/16
The question tells us that Mallory's 2 years old than three times her brother Jake's age, but let's just start by saying she's 2 years older than <em>some age. </em>What would that look like? Well, we'd be taking some number and adding two to it, so something like this:
Mallory's age = (some age) + 2
What is that age though? The problem tells us it's three times Jake's age, j. We can write that as 3 × j, or 3j, to save space. Filling in our blank, we can write the expression for Mallory's age as 3j + 2
Answer: 29544.26 mm^2
Step-by-step explanation:
The formula is A = pi R squared.
If I use 3.14 for pi, then it would look like 3.14(97)^2
Which equals 29544.26 mm^2
Answer:
3/2 (or 1 1/2)
Step-by-step explanation:
-4 1/6 + 5 2/3 (express as improper fractions)
= -25/6 + 17/3 (convert fractions common denominator i.e 6)
= -25/6 + (17/3)(2/2)
= -25/6 + (17 x 2)/6
= -25/6 + 34/6
= 9/6
= 3/2
=1 1/2
