Answer:
a. The price of an apple is $0.5 and that of a banana is $0.8
b. 4
Step-by-step explanation:
Form simultaneous equations from the information.
For 5 apples and 4 bananas, and the total comes to $ 5.70 this can be;
5 a + 4 b = $5.70----------i
After he puts back 1 apple and 2 bananas, the equation will be;
4 a + 2 b = $3.60 -------------ii
Solve the two equations simultaneously as;
{5 a + 4 b = 5.70 }4 ---------making the a terms equal to eliminate them
{4 a + 2 b = 3.60}5
20 a + 16 b = 22.80 -------subtract the b terms
20 a + 10b = 18.00
6 b = 4.80
b= 4.80/ 6
b=$ 0.8
Using equation i :
5a + 4b =$5.70
5a + 4*0.8 = 5.70
5a + 3.2 = 5.70
5a = 2.5
a = 2.5 / 5
a=$0.5
The price of an apple is $0.5 and that of a banana is $0.8
b.
Let the number of apples be ------x
Let the number of bananas be-----x
This is because the target is equal numbers;
Form an equation for total cost as;
0.5 x + 0.8 x = $6
1.3 x = 6
x = 1.3 / 6 = 4.62
Maximum number of bananas to buy = 4
Maximum number of apples to buy = 4
However, he will have $0.8 remaining

ANSWER THIS PLS!!!!
The constant velocity motion formula can be expressed as x = x0 + vt
where x is the location of the object at time t, xo is where the object begins, and v is the constant velocity. This is an example of a linear equation.
Suppose we’re collecting data on an object that we know has a constant velocity. We observe the object being 40m away from us at time 4. 10 seconds later at time 14, we make another observation and notice the object is now 70m away.
Using this data, and the constant velocity motion formula, determine an equation that models the object’s path.
Answer and Step-by-step explanation: With the constant velocity motion formula, we can determine constant velocity of the object in motion whose data we collected:
x = x₀ + vt
Velocity can be calculated as:
[tex]v=\frac{x-x_{0}}{t}[/tex]
[tex]v=\frac{70-40}{10}[/tex]
v = 3 m/s
The beginning of the data collect, object is 40m away, then x₀ = 40.
So, equation modeling the object's path is x = 40 + 3t.

at a hot dog stand they serve regular and footlong hot dogs at a ratio of 5 to 3 based on this ratio how many footlongs hot dogs will be served there is a total of 120 hot dogs served. A. 45 footlong hot dogs, B. 75 footlong hot dogs, C. 72 footlong hot dogs
Answer:
45
Step-by-step explanation:
Ratio is 5:3
So total ratio "parts" is 5 + 3 = 8
In total there are 120 dogs served, so each part is:
120/8 = 15 dogs
Since, footlong hot dogs are "3" parts, and each part is 15 dogs, there will be:
3 * 15 = 45 footlong hotdogs
Answer:
45

Stephan added 26 new contacts to his phone list. He had to delete 16 old contacts before he could add any more. Stefan now has a total of 100 contacts. Let c represent how many contacts he had on his phone list before he updated it. Write an equation and then solve for c.
Answer: 26-16= c
c=10
Step-by-step explanation:
Answer: 90c-16c+26c=100c
Stephan had 90 contacts before he deleted 16 then added 26 more how it works is Stephan had 90 right, then proceeded to delete 16 which left him with 74 contacts after he then added 26 more contacts so he know has 100 contacts.

Answer:
noo
Step-by-step explanation:
no, 35 divided by 7 is 5 and 42 divided 7 is 6 it should actually be 5:6
Abigail is incorrect and the correct ratio of the number of boys in 6th grade to the number of girls in 6th grade is 3:4
What is Ratio?A ratio is an ordered pair of numbers a and b, written a / b where b does not equal 0.
Given,
The number of boys in 6th grade is 30
The number of girls in 6th grade is 40.
The ratio of the number of boys in 6th grade to the number of girls in 6th grade is 30:40
30/40
Divide numerator and denominator by 10
3/4
The ratio of the number of boys in 6th grade to the number of girls in 6th grade is 3:4.
But Abigail says that the ratio of the number of boys in 6th grade to the number of girls in 6th grade is 4:3, which is not true.
Hence, Abigail is incorrect and the correct ratio of the number of boys in 6th grade to the number of girls in 6th grade is 3:4

The number of visits to public libraries increased from 1.3 billion in 1998 to 1.5 billion in 2002. Find the average rate of change in the number of public library visits from 1998 to 2002.
Answer:
A = 0.05 billion visits per year
Step-by-step explanation:
Given that,
The number of visits to public libraries increased from 1.3 billion in 1998 to 1.5 billion in 2002.
We need to find the average rate of change in the number of public library visits from 1998 to 2002.
So,
[tex]A=\dfrac{1.5-1.3}{2002-1998}\\\\A=0.05\ \text{billion visits per year}[/tex]
Hence, the required average rate is 0.05 billion visits per year.
