Answer:
Peggi put a total of 18 hair bows in the bag
Step-by-step explanation: There at six bags with an unknown amount of hairbows in each bag. You add 2 to each bag and you will end up getting 12 hairbows from her sister because 6x2=12. then you subtract the total (30) from her sister Toris amount (30-12) this equals 18.
Answer:
Step-by-step explanation:
Dividing both sides by -7.
There is only one solution that satisfies the equation.
Answer:
80
Step-by-step explanation:
The equation of finding a slope is y2-y1/x2-x1.
y-5/-7-(-21)=5
y-5/-7+21=5
y-5/15=5
y-5=75
y=80
The Pythagorean Theorem states that for right triangles:
a^2=b^2+c^2
a= the hypotenuse
b and c equals the other two sides.
In this case we are given the hypotenuse so we can rearrange the equation to look like this b^2=a^2-c^2 (I subtracted c^2 from both sides). I know a and c so I can solve for b.
We get rid of a square by implementing a square root on both sides and get:
b=sqrt(a^2-c^2) .... b=sqrt( (sqrt(34))^2 - 3^2)
b= sqrt(25) ..... b=5
