Answer:
7
Step-by-step explanation:
the area of a triangle is base*height/2. so, if the area is 14 mm^2, we have to figure out how much the area would be without dividing by 2. the opposite of division is multiplication, so 14*2=28. now that we know how much the area would be if we didnt divide by 2, we have to figure out the base. the equation is:4x=28. we divide 4 on each side and we get x=7.
X=-1.8
To solve first use the distributive property to change the equation to -2x+1 1/3+1=5
Then you subtract 1 from 5 so then the equation looks like this: -2x+1 1/3=4
Next subtract 1 1/3 from 4 to get 3.6
then divide it by -2 and you get -1.8
Answer:
Jessica spent 10 months in Spain and 8 months in Colombia.
Step-by-step explanation:
Let x be the number of months Jessica lived in Spain, then she lived 18 - x months in Colombia.
She learned an average of 160 words per month when she lived in Spain, so she learned 160x words in Spain.
She learned an average of 200 words per month when she lived in Colombia, so she learned 200(18-x) words in Colombia.
In total, she learned a total of 3,200 new words, thus
Jessica spent 10 months in Spain and 8 months in Colombia.

Answer:
D. y = | x | + 7
Step-by-step explanation:
The + outside of the absolute value equation means there is a vertical shift up. So since there is a +7 that means there is a vertical shift 7 units up.
