Let <span>p time in minutes speaking Polish
</span>let <span> h </span> time in minutes speaking <span>Hungarian
</span>
<span>p + h = 5 equation 1
</span><span>190 p - 150 h = 370 equation 2
</span>
multiply eq. (1) by 150 (both sides) <span>
15 0p + 150 h = 750
190p -150 h = 370
add the two eqiations we get :
</span><span>190 p + 150p = 370 + 750
</span><span>
340 p = 1120
p= 1120/ 340 = 3.29
</span><span>3 minutes speaking Polish and 2 minutes speaking Hungarian.
</span>make sure if the number 370 ?? i think it is wrong , it can be 270 because i get a point in the answer
<span>To find the total loss for this play, take the two values, find their signs (positive or negative), then sum them. In this case, the play itself resulted in a movement of -12.5 yards, and the penalty added a -5 yard movement to the result. This would lead to a total movement of (-12.5 + [-5]), or -17.5 yards.</span>
Answer:
The 85 term of the arithmetic sequence would be 983
Step-by-step explanation:
Use the formula: an=a1+(n−1)d
an=a1+d(n-1)
a85= -25+(85-1)12
a85= -25+1008
a85=983
Step-by-step explanation:
find the area of thw shaded region using math
Converting celsius to farenheit
C * 1.8 + 32
220 * 1.8 + 32 = 396 + 32 = 428 F....so 220 C = 428 F
so he set the oven for 428 F, when it was supposed to be set for 400 F
428 - 400 = 28.....28 degrees too hot
