Answer: 72.4
Step-by-step explanation:
Fraction of six-grade students that have at least one pet = 2/5
Number of sixth graders at Brunswick Elementary school = 181
The number of sixth graders that own own pets will be:
= 2/5 × 181
= 72.4
(X1=1, y1=7) and (x2= -4, y2 =-8)
Slope = ( y2-y1)/(x2-x1)= (-8-7)/(-4-1)= -15/-5=3
Slope is 3
Answer:
87.0
Step-by-step explanation:
17.4
17x5=85
.4x5=2.0
85+2.0=87.0
Answer:
As follows, (shortened)
Step-by-step explanation:
1.AB=CD (Given)
2.AB+BC=CD+BC ( By additive property, adding BC to both sides)
3.AB+BC=CD+DE (Given, BC=DE, By substitution property replacing BC by DE)
4.AC=CE(By segment addition, and substitution property)
