avanturin [10]

Answer:

$Total = 38\frac{11}{12}\ miles$

Step-by-step explanation:

Given

$First\ Route = 12\frac{2}{3}\ miles$

$Second\ Route = 10\frac{3}{4}\ miles$

$Third\ Route = 15\frac{1}{2}\ miles$

Required

Determine the total miles

$Total = First\ Route + Second\ Route + Third\ Route$

$Total = 12\frac{2}{3} + 10\frac{3}{4} + 15\frac{1}{2}$

Convert to improper fractions

$Total = \frac{38}{3} + \frac{43}{4} + \frac{31}{2}$

Take LCM

$Total = \frac{152 + 129 + 186}{12}$

$Total = \frac{467}{12}$

$Total = 38\frac{11}{12}\ miles$

Over the last 3 months, Janet exercised a total of 101 hours. She exercised 4 hours more during the second month than the first

olganol [36]

In 1st month let she exercised h hours

in second month she exercised h+4 hours

in third month she exercised h+4-3=h+1 hours

Now

h+h+4+h+1=101
3h+5=101
3h=96
h=32hours

Find the value of x and each angle if m angle SOP= (7y-2) and m angle SOR = (5y+14)

Semmy [17]

Answer:

x = 14

m∠SOP = (7x - 2)° = 96°

m∠SOR = (5x + 14) = 84°

Step-by-step explanation:

`From the given picture,

Angle SOP and angle SOR are the linear pairs.

Therefore, sum of these angles will be equal to to 180°.

m∠SOP + m∠SOR = 180° -----(1)

Since, m∠SOP = (7x - 2)° and m∠SOR = (5x + 14)°

[There is a misprint in this question. There should be x in place of y in the measures of the angles]

By substituting these values in the equation (1),

(7x - 2) + (5x + 14) = 180

12x + 12 = 180

12x = 180 - 12

12x = 168

x = $\frac{168}{12}$

x = 14

m∠SOP = (7x - 2)° = 96°

m∠SOR = (5x + 14) = 84°

zaharov [31]

X sqrd-4x+y sqrd-10= -29
y sqrd-10y = -29-X sqrd + 4X
y(y-10) = -29-X sqrd +4X
y = - 29 -X sqrd +4X ÷( y- 10)
