Answer:
3y+4x=5
Step-by-step explanation:
step 1
Find the slope
we have
(–7, 11) and (8, –9)
m=(-9-11)/(8+7)
m=-20/15
m=-4/3
step 2
Find the equation of the line into point slope form
we have
m=-4/3
point (-7,11)
substitute
y-11=-(4/3)(x+7) ----> equation of the line into point slope form
Multiply by 3 both sides
3y-33=-4(x+7)
3y-33=-4x-28
3y+4x=33-28
3y+4x=5 -----> equation of the line into standard form
Answer:
i. 30.5m
ii. 930.25m²
iii. Rs. 37,218
Step-by-step explanation:
Perimeter of a square = 4 * Length
i. Length = Perimeter/4
= 122/4
= 30.5 m
ii. Area = Length * Height
= 30.5 * 30.5
= 930.25 m²
iii. Cost of growing grasses at Rs. 40 per m²
= 930.25 * 40
= Rs. 37,218
Answer:
percentage of seventh graders on the team is 20%
Step-by-step explanation:
given data
total girl = 25
soccer team = 5
to find out
percentage of seventh graders on the team with two different way
solution
we first make here a tape diagram
there in begin by divide the tape diagram into 5 equal part
and Each part represent 5 girls
so divide the 100% into 5 equal sections as show in figure below
and
another way is
percentage of seventh graders on the team is = 
× 100%
percentage of seventh graders on the team is 20%
Answer:
The answer is 20
Step-by-step explanation:
2x=6 and then 7x2=14 then 14+6=20
Answer:
-22/3
Step-by-step explanation:
to convert a mixed number to an improper fraction:
whole number × denominator + numerator
keep the denominator
-8 × 3 + 2
-24 + 2
-22
keep denominator
-22/3
