1*8=8
Chris is 8
Answer:
8
Step-by-step explanation:
If we say the there ages is x
it would be x+3x+3x=56
and lets say the x=8
then 8+24+24
That would mean Chris should be 8.

Mara's family is driving to her grandmothers' house. The family travels 239.4 miles be-
tween the hours of 9:10 a.m. to 1:40 p.m. Write an equation that Mara can use to deter-
mine their average rate of travel, rounded to the nearest mile per hour.
Use the given numbers and operations to complete an equation.
Answer:
Give brainliest please! The answer is 53.2 mph
Step-by-step explanation:
Mara's family travels 239.4 miles between the hours of 9:10 a.m. to 1:40 p.m.
1:40 p.m. is 13:40.
Thus, they traveled for
13 hours 40 minutes - 9 hours 10 minutes = 4 hours 30 minutes
that is hours.
Use formula:
where
D = distance
r = rate
t = time.
In your case,
D = 239.4 miles
t = 4.5 hours

Which equation demonstrates the associative property of multiplication?
Answer:
A
Step-by-step explanation:
The parentheses are switched around, making the answer still the same. However, for Answer choice C, it is Commutative Property because the factors are switched around.
=====================================================
Explanation:
The equation shown for choice A is in the form p*(q*r) = (p*q)*r which is the general format for the associative property of multiplication.
In this case, p = 2.5, q = 1/5 and r = 2/3.
The order of p,q,r stays the same while the parenthesis shift around. The stuff in the parenthesis is done first before anything else. Though with multiplication, the order doesn't matter which is why we can freely shift the parenthesis like this.
Addition has a similar rule which says p+(q+r) = (p+q)+r.
what is this pls help me
Answer:
distance would make the most sense
Answer:
Distance
it's because distance cannot be negative, always making it positive, or the absolute value.

A strawberry farm had 7,200 plants in total, one field had 18 rows of 200 plants ; the other field had 9. Rows of
Answer:
We have a total of 7200 plants.
The plants are distributed in one field with 18 rows of 200 plants and another field with 9 rows of N plants.
Where we want to find the value of N.
The total number of plants in the rows is:
"number of rows times number of plants in each row."
Then the total number of plants is:
18*200 + 9*N
And we know that we have a total of 7200 plants, then:
18*200 + 9*N = 7200
9*N = 7200 - 18*200 = 3600
N = 3600/9 = 400
Then the plants are distributed in 18 rows of 200 plants for one field, and 9 rows of 400 plants in the other field.

c
wholesaler C
d
wholesaler D
Answer:
Wholesaler A.
Step-by-step explanation:
First, put the pounds and dollars into fraction form. Then simplify those fractions. Finally, convert the fractions into decimals and compare the unit prices for each wholesaler. Whichever one is the lowest has the best price.

Answer:
29.3
Step-by-step explanation:
to find average you find the sum of all the minutes she practiced and divide it by the total amount of day she practiced.
first we have to find the sum of the minutes she practiced:
20+30+40+38+25+22+39+22+26+31
this equation is equal to 293 minutes she practiced in total. Now we have to divide this by the total amount of days she practiced whice according to the data is 10! So:
293/10 =29.3

Ron cycled 510km last week he was under the rain for the 25percent of his journey how far did he travel under the rain? A b c d answer rain
Answer: 127.5km
Step-by-step explanation:
We are informed that Ron cycled 510km last week and that he was under the rain for the 25percent of his journey.
The distance travelled did under the rain will be gotten by multiplying 25% by 510km. This will be:
= 25% × 510
= 0.25 × 510
= 127.5km
He was in the rain for 127.5km

Answer:
(-1,3)
Step-by-step explanation:
3x + 6y = 15
6x + 6y = 12 Subtract
-3x = 3 Divide by 3
-x = 1 multiply by - 1
x = - 1
3x + 6y = 15
3(-1) + 6y = 15
-3 + 6y = 15 Add 3 to both sides
-3+3 + 6y = 15 + 3
6y = 18 Divide by 6
y = 18/6
y = 3
(-1,3)

A line passes through the point (-6,9) and has a slope of -5/2 . Write an equation in point-slope form for this line.
Answer:
y-9=-5/2(x+6)
Step-by-step explanation:
y-y1=m(x-x1)
y-9=-5/2(x-(-6))
y-9=-5/2(x+6)
An equation in point-slope form for this line would be y-9=-5/2(x+6).
What is the Point-slope form?The equation of the straight line has its slope and given point.
If we have a non-vertical line that passes through any point(x1, y1) has gradient m. then general point (x, y) must satisfy the equation
y-y₁ = m(x-x₁)
Which is the required equation of a line in a point-slope form.
Thus,
y-y1= m(x-x1)
A line passes through the point (-6,9) and has a slope of -5/2 So,
y-9=-5/2(x-(-6))
y-9=-5/2(x+6)
Hence, an equation in point-slope form for this line would be y-9=-5/2(x+6).

The answer is -5
Step-by-step explanation:
First, let's understand about what are rational number and Integer.
Both rational and Integer are part or rather say subset of Real Number. Real Number can be broken into these categories:
Rational And IrrationalI will not talk about Irrational since It is a bit off-topic for the question.
Rational can be broken into:
Integer (Positive, Zero and Negative) FractionInteger is a subset of Rational Number and Real Number. But what is really Integer?
Integer is a whole number or any numbers that don't have decimal, fraction. Integer can be ...,-4,-3,-2,-1,0,1,2,3,4,...
The three dot symbol refers to being endless or countable infinity.
Now that you see Integer cannot be fraction, decimal.
Therefore, the answer is -5
Answer: B) -5
Step-by-step explanation:
An integer is like a whole number, but it also includes negative numbers (e.g. -300, -5, 0, 5, 6, 100).
You can write a rational number as a ratio of two numbers (e.g. 7/1, 1/3, -2/3, -4/7).
None of the answer choices given are integers, except -5. It is also a rational number, since it can be written as -5/1.

a washing line is attached at point a and beyond two vertical post standing on horizontal ground .
Point a is 2.1 m above the ground on one post
point b is 1.7 metres above the ground on the other post
the horizontal distance between the two posts is 6 m
calculate the distance ab
give your answer correct to 3 significant figures.
9514 1404 393
Answer:
6.01 m
Step-by-step explanation:
Apparently, the washing line is the hypotenuse of a right triangle with sides (2.1-1.7) = 0.4 m and 6 m. The Pythagorean theorem can be used to find its length.
ab = √(0.4² +6²) = √36.16 ≈ 6.0133
The distance ab is about 6.01 m.
