The difference of a number and seven is x - 7. So twice that, would be:
2(x - 7)
2x + 2y = 6 . . . . . (1)
x + 3y = -1 . . . . . (2)
(1) x 3 => 6x + 6y = 18 . . . . . (3)
(2) x 2 => 2x + 6y = -2 . . . . . (4)
(3) - (4) => 4x = 20
x = 20/4 = 5
Answer:
<h2>47°</h2>
Step-by-step explanation:
Given m∠JML = 80 and m∠KML = 33, to calculate the value of angle m∠JMK, we will apply the formula since all the angles are all acting at point M.
m∠JML = m∠JMK+m∠KML
Substituting the values given into the equation;
80 = m∠JMK + 33
subtract 33 from both sides of the equation
m∠JMK = 80-33
m∠JMK = 47°
<em>Hence the value of angle m∠JMK is 47°</em>

Answer:
4092
Step-by-step explanation:
r = 2
a1 = 4×(2)^(1 - 1) = 4
S10 = a1×((1 - r^10)/(1 - r)
= 4×((1 - 2^10)/(1 - 2))
= 4×((1 - 2^10)/-1)
= 4×(-(1 - 2^10))
= -4×(1 - 2^10)
= -4 + 4 × 2^10
= -4 + 2^2 × 2^10
= -4 + 2^12
= -4 + 4096
= 4092
