1 -
3 cups left.
2-
David biked a total of 158 miles (option C)
Why?
- First exercise:
To solve the problem we need to consider that for each 1/2 cup of cornmeal, we will have 6 corn muffins.
So, calculating we have:

We can see that, if each 1/2 cups can give us 6 corn muffins, 2 cups can give us 24 corn muffins.

Hence, there are 3 cups left.
- Second exercise:
We can solve the problem by multiplying or adding the fractions according to the number of dots assigned to each one.
So, calculating we have:


Hence, we have that David covered a total 158 miles. (Option C)
Have a nice day!
Cow : 9 x 10^2 = 9 * 100 = 900
whale : 1.8 x 10^5 = 1.8 * 100,000 = 180,000
180,000/900 = 200
The blue whale has about 200 times more mass <==
Answer:
x= -8
collect like term than divide both sides
6x-4x = -20+4
2x= -20+4
2x=-16
x= -8
First thing we are going to do to solve this is to subtract 1.5 from both sides so:
<span>5x+1.5−1.5</span>=<span>7−1.5
</span>5x<span>=5.5
</span>Next we are going to di<span>vide from both sides by 5 so:
</span><span><span>5x/</span>5</span>=<span>5.5/<span>5
Finally your final answer shall be:
</span></span><span>x=1.1
I hope this helps!</span>
Foil is just like distributive meathod rememebering meathood
so foil is
First
Outer
Inner
Last
so if you had
(a+b)(c+d)
you would do
First
a times c
Outer
a times d
Inner
b times c
Last
b times d so
we have
(b-3)(b+9)
FIRST
b times b=b^2
Outer
b times 9=9b
Inner
-3 times b=-3b
Last=-3 times 9=-27
add
b^2+9b-3b-27
add like terms
b^2+6b-27
answer is A
