Answer:

1. w = 15

2. b = 4.8

3. s = 9.7

4. p =15

5. m = -3.2

Step-by-step explanation:

1.w + 10 = 25

we have to find the value of w, so moving 10 from left side to right side

w= 25 - 10

w = 15

2. 7.2 + b = 12

we have to find the value of w, so moving 7.2 from left side to right side

b= 12 - 7.2

b= 4.8

3. 5.3 + s = 15

s= 15 - 5.3

s= 9.7

4.p + (-25) = -10

p-25 = -10

p= -10 + 25

p= 15

3. m + (-1.6) = -4.8

m - 1.6 = -4.8

m = -4.8 + 1.6

m= -3.2

Answer:

1. w=15

2. b=4.8

3. s=9.7

4. p=15

5. m=-3.2

Step-by-step explanation:

1. For the equation w + 10 = 25, subtract 10 from both sides:

w + 10 -10= 25-10\\w=15

2. For the equation 7.2 + b = 12 subtract 7.2 from both sides:

7.2 + b -7.2= 12-7.2

b=4.8

3. For the equation 5.3 + s = 15  subtract 5.3 from both sides:

5.3 + s-5.3 = 15-5.3\\s=9.7

4. For the equation p + (-25) = -10, multiply signs and then add 25 to both sides of the equation:

p -25= -10\\p - 25 +25= -10+25\\p=15

5. For the equation  m + (-1.6) = -4.8,  multiply signs and then add 1.6 to both sides of the equation:

m -1.6+1.6 = -4.8+1.6\\m=-3.2

vova2212 [387]
1. 27 - 3 (because 3 are left over) = 24. Then, 24 ÷ 6 = 4 children. 

2. If Mina has £7.20, that means she has 720 pence. If half is given to her brother, then she has £3.60 left. (720 ÷ 2 = 360 pence, which is £3.60) 

3. 17 × 10 = 170
2 × 20 = 40
170 + 40 = 210, which is £2.10

The table shows the number of calories in four meals and the cost of each meal.
Aleksandr-060686 [28]

Answer:

A weak negative correlation

Step-by-step explanation:

correlation, r = \frac{∑(y-\alpha)(x-\beta  }{\sqrt{∑(y-\alpha)^2∑(x-\beta )^2 } }

where,

\alpha = \frac{∑y}{n} \\\beta =\frac{∑x}{n} \\∑ = summation

\alpha = \frac{3230}{4} = 807.5\\\\\\\beta =\frac{46}{4} = 11.5

therefore,\\\\r= -0.12924

This represents a weak negative correlation

(Please i need help) The expression p - 0.15p can be used to calculate the final cost of an item that has a price of p and is
garri49 [273]

Answer:

Final cost of the item is $19.55

Step-by-step explanation:

Expression representing the final cost of an item with original price = $p and discount = 15% will be,

Final cost = (p - 0.15p)

If the original price p = $23

By substituting p = 23 in the expression given,

Final cost after discount = 23 - (0.15)23

                                         = 23 - 3.45

                                         = $19.55

Therefore, final cost of the item is $19.55
